The magnetic field around the earth runs through the center of the earth and has the positive end at the arctic pole and the positive end at the antarctic pole
magnets have north and south poles ( positive and negative) that means that they align themselves with the negative end pointing north and the positive end pointing south
that is right --but any compass you have the N is pointed on the negative end and that is the direction where the north is

Why is earth the only planet with life?


We don't know that the Earth is the only planet with life. It's the only planet we know of with life, but that doesn't mean that there aren't any others. There are many, many other planets out there in the universe. Some of them almost certain do have life.

What is a hot plate stirrer?


From Wikipedia: A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (also called "flea") immersed in a liquid to spin very quickly, thus stirring it. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid. Since glass does not affect a magnetic field appreciably (it is transparent to magnetism), and most chemical reactions take place in glass vessels (i.e. see beaker (glassware) or laboratory flasks), magnetic stir bars work well in glass vessels. On the other hand, the limited size of the bar means that magnetic stirrers can only be used for relatively small (under 4 liters) experiments. They also have difficulty dealing with viscous liquids or thick suspensions. For larger volumes or more viscous liquids, some sort of mechanical stirring is typically needed.

I get a humming sound when I plug my Gibson SG straight nto the amp. The noise fades and strengthens depending the positioning of the guitar in relation to the amp.


Your Gibson is sensitive to magnetic fields You need to keep the guitar about 10 feet away from the amp as the power transformer is radiating magnetic fields that is causing the hum. Solutions: there aree several... most are NOT practical... such as encasing the transformer of the amp in Mu-Metal shielding. Changing the transformer to a toroid type (they should deliver them that way) encase the amp in a thick steel cabinet... all this is ridiculous... putting distance between teh amp and the guitar is probably the only practical solution. The level given any particular orientation should fall off with the square of the distance. Note that OTHER stage equipment also will have transformers that radiate. Much of the new amps do NOT have power transformers that run at low frequency so they don't have this problem. Marshal is old school and they use the older power supply designs that radiate the magnetics.

What is the difference between an electromagnet and a bar magnet????


A bar magnet is permanently magnetic, thought not usually especially strong. An electromagnet is caused to be magnetic while energised by a power source. Many bar magnets are created by being subjected to an electromagnetic field.

Cant find wer the spark plugs for a 2001 hyundia sonota


Could be a cover over the spark plugs or plugs have coil on plug system: Ignition System WARNING
To avoid personal injury and/or vehicle damage, refer to the service precautions at the beginning of this section.
General Information NOTE: For information on understanding electricity and troubleshooting electrical circuits, please refer to chassis electrical.
Coil on Plug (COP) System
The coil over plug system was developed so that spark and spark timing could be better controlled on an individual cylinder basis. Each cylinder has an ignition coil mounted directly above the spark plug on the cylinder head cover. A short suppresser/connector replaces the spark plug wire and links the coil to the plug. There are different methods used for primary triggering. Some manufacturers use a combination coil/module, which means each coil has its own control circuit that is activated by the PCM. Others use remote mounted modules to trigger the coils.
Each individual coil is allowed to saturate while all other cylinders fire. For a V-8 engine, this allows a period of seven firing events for coil saturation, compared to three events for the same V-8 engine with a waste spark system. The coil over plug system also benefits from a minimum amount of energy lost, due to the resistance of spark plug wires.
Distributor System
If a distributor is not keyed for installation with only one orientation, it could have been removed and installed improperly and then rewired. The new wiring arrangement would maintain the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes of the current plug wire locations and orientation of the distributor cap.
Magnetic Sensor / Pick-Up Coil
The magnetic sensor in electronic ignition system is made up of a small coil of wire wrapped around an iron core, a permanent magnet and a toothed wheel called a reluctor. These sensors can be found mounted in a distributor, or at the front, middle, or rear of the crankshaft or camshaft, and are two-wire sensors.
The permanent magnet produces a magnetic field that passes thru the center of the pick-up coil. As the reluctor turns, the small teeth enter the magnetic field. Because the metal is a better conductor for the field than the air between the magnet and reluctor, the field strength begins to increase and reaches its maximum when the reluctor teeth are closest to the sensor. An increase in magnetic field induces a positive voltage to the module. As the teeth leave the magnetic field, the decrease in pole strength induces a negative voltage into the module. This alternating positive and negative voltage causes a small AC current. This alternating current after passing through an analog/digital converter is used by the module or engine controller to trigger the primary circuit.
Hall-Effect Device
Another device that can be used to create a triggering signal is a hall-effect device. A hall-effect device can be thought of as a solid-state On/Off switch. The hall-effect switch is a three-wire device that must receive a power and ground. The hall-effect switch is used in conjunction with an interrupter ring with a series of slots or openings cut into it. Depending on the application, these slots are spaced around the ring in a specific configuration. As the ring rotates, the slots pass between the hall-effect switch, and alternately turns the voltage off and on. When a slot aligns with the hall-effect switch, the controller sees voltage on the signal line. When the area between slots passes the hall-effect switch, the signal is pulled low. This results in a voltage of 0V–0.1V at the controller.
The rotation of the interrupter ring causes the signal to toggle, which causes a continual series of digital pulses on the signal line. This digital pulse is the timing signal that is used by the ignition module or engine computer to open and close the primary circuit. The controller processes these pulses as the RPM signal.
Photo-Optical
Another device used to create a triggering signal is the photo optical sensor. Inside the distributor, there are pick-ups called the Reference pick-up and the Sync pick-up. Each pick-up has a Light Emitting Diode (LED) and a phototransistor. A slotted disc rotates between the pick-ups. The pair of LED’s and phototransistors generates crankshaft position and RPM signals (high and low-resolution signals). The LED’s are powered by a 9- or 12-volt source (depending on manufacturer). Each phototransistor is used to turn a 5-volt signal from the engine controller on and off.
If we look at the optical distributor used in the Chrysler 3.0L engine as an example, there are two areas of slots cut into the disc. The outer diameter of the disc, which generates the high-resolution signal, contains 350 slots. Each of these slots represents 1 degree of crankshaft rotation. An area of approximately 3/8" with no slots represents the remaining 10 degrees. The inner portion of the disc is the low-resolution signal and contains six 60-degree slots. Each of these slots represents the piston’s top dead center position for each cylinder. The controller uses the high-resolution signal to regulate spark timing up to 1200 RPM. This ensures timing accuracy, since crankshaft speed fluctuations are most likely to occur because of the firing pulses during cranking and idle. The low-resolution signal is used for injector firing, as well as ignition timing above 1200 RPM.
As the slots pass between the LED’s and the phototransistors, the transistors are toggled on and off. This occurs as the light beams from the LED’s are alternately interrupted. When the light beam from the LED strikes the phototransistor, the transistor turns on. This causes the 5-volt signal to be pulled low (0V–0.1V). When the rotating disc blocks the light beam, the transistor turns off. This causes the 5-volt signal to remain high.
Ignition Coil
The heart of the automotive ignition system is the ignition coil. The ignition coil is a step-up transformer, since it boosts battery voltage to the high voltage that is necessary for proper combustion.
The ignition coil consists of a primary winding and secondary winding wrapped around a soft iron core. The primary winding is made up of several hundred turns of heavy wire, while the secondary winding consists of thousands of turns of fine wire. The iron core is used to conduct magnetic lines of force efficiently.
When current flows through the primary winding, a magnetic field is created. The more time current is permitted to flow, the stronger the magnetic field becomes. When the current is turned off, the magnetic field collapses causing a high voltage to be induced in the secondary winding through the process of induction.
A few hundred volts will be generated in the primary winding because of the collapsing magnetic field across the heavy primary wire. However, as the magnetic lines of force cut across the thousands of turns of fine wire in the secondary, a far greater voltage is produced. The production of primary voltage is called self-induction, since the primary winding essentially magnifies its own initial voltage when the magnetic field collapses.
Related Symptoms
Faulty ignition system components along with loose connections, bad grounds, high resistance or opens in the circuit, may cause the following symptoms:
  • No start condition
  • Stalling after cold start
  • Stalling after hot start
  • Surging off idle
  • Extended crank time when engine is cold
  • Unstable idle
  • Running rough during off idle acceleration
  • Bucking
  • Hesitation
  • Stumble
  • Poor fuel economy
  • Spark knock

I have purple heads on my tv


Maybe you have some kind of magnetic material on top of the TV. TV screens respond to magnetic field. If the problem is not caused by a magnetic material being near it, then it is the degauss (meaning demagnetize) circuit inside. You can also degauss a screen using electromagnet. If placed around the screen of the TV in the right way. I have never used a magnet to demagnetize a TV screen, but maybe orienting the magnet at just the proper angle may also demagnetize it by cancelling the magnetized area. You can also make a TV screen demagnetizer using a loop maybe made out of plastic tube and winding enamelled wire onto it. The loop has to be about the size of your TV screen. Make sure you put tape over the whole thing, and connect a plug so you can plug it to the ac outlet. Once plugged in, the ac current will produce magnetic field to cancell out the magnetized area, when you wave the loop around your screen. I once made this as one of my tools when I worked at a TV repairshop.

Diagonal RGB lines


It might just need degaussing. If the monitor is equipped with a degauss button, try pressing it. If not, it might eventually go away with time - sometimes when CRT monitors are moved and change orientations odd color distortions due to magnetic fields result. After a while the magnetic field fades and the colors will be back to normal.

Otherwise, upgrade to an LCD - easier on the eyes, and a lot easier on the back. :)

Interference?


The picture tube on a TV can be magnitized by the Earth's magnetic field. The noise heard when you turn a TV on (usually followed by a static noise on the face on the TV) is called degauss. What this does it remove any magnetic variations on the tube due to things like the magnetic field and speakers. However, changes to the TV in orientation to the Earths magnetic field will cause the tube to have a magnetic bias. This is most prominent when turned 90 degrees. The easy way to clear this is to turn the TV off for a little while and then turn it back on. But remember that any movement once it is on can cause the discolorations to reappear. My suggestion would be to turn the tv after you've moved it to the location you'd like to view it.
