Comp Quest 22 SPI 0807.12.3
... A compass points to the north because Earth itself is one giant magnet. In fact, Earth behaves as if it has a bar magnet running through its center. The poles of this imaginary magnet are located near Earth’s geographic poles. If you put a compass near a bar magnet, the marked end of the needle poin ...

What is magnetism
... magnetic fields result from electron flow through a conductor. In the case of permanent magnets, it’s the spinning of the electrons that creates magnetism, not their movement through a conducting material. You know that the Earth is a great big magnet. Well, electrons are teeny tiny ones. They have ...

Electric field trapping of a magnetic domain wall
... The frontier between those two regions is called a magnetic domain wall and within the wall the magnetisation rotates progressively to minimize the energy Fig. (1a). We have demonstrated that when the electric field is switched on, the domain wall is pinned when it reaches the edge of the electrode ...

Magnetism
... An electric motor uses a magnet to exert a force on a current-carrying coil of wire. An electric motor uses brushes and an armature to reverse the flow of current so that the coil of wire can rotate 360o. One magnet repels the armature half a turn, the other attracts half a turn to make it move. ...

615-0185 (20-010) Instructions for Dip Needle
... a very useful tool in iron prospecting. Today this method is not as accurate as computer modeling and high tech scanners, but in early years it was indispensable. Your dip needle is equipped with banana jacks on the gimbal. If you connect a low voltage source to these, the gimbal will become electri ...
