A) What is an electromagnet? B) What causes the magnetic field of the earth? C) What causes the northern and southern lights? What causes the magnetic field of the earth? What is different about the magnetic poles of a common refrigerator magnet and the common bar magnet?
Once a head arrives at a certain location on a platter, an electromagnet produces a magnetic field, which aligns data-carrying domains in the underlying track. Each domain can be aligned in one of two possible directions — 1 or 0. As these alignments change, they form patterns that ...

electromagnet A magnet created by wrapping a coil of wire with a current around a ferromagnetic core. A solenoid with a ___core is called an electromagnet. ferromagnetic An electric current produces a(n) magnetic field Just as in a bar magnet, the magnetic field of a wire with a current...
An electromagnet is generally made from coils of wires that act as a magnet when an electric current passes through them. Solenoids are devices of a thin coil of wire wrapped around a magnetic object that, when a current is sent through them, they will give off a magnetic field. In the ...
The electromagnet attracts the armature. Contact The combination of fixed and movable contacts opens and closes the control circuit. MOS FET Relay One of the major characteristics of a MOS FET relay is that it utilizes semiconductor so the contacts do not mechanically open/close. As a result, ...
