Motors use magnetic fields to rotate a shaft. As the electric current going to the motor varies–all generated currents do, it causes the rising and falling magnetic fields to push the core of the motor around. Motors are ubiquitous–at least a dozen are in your car, there is one in eve...

How are magnetic fields and electric fields related? How strong is electromagnetic force? What is the frequency of the Earth's magnetic field? How is the strength of the magnetic field determined? What is B in Ampere's law? What subatomic particle has a charge of 1?
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 ...
Electromagnetic waves form when an electric field merges with a magnetic field. In directional form, magnetic and electric fields of an electromagnetic wave are perpendicular to one another and to the direction of the wave. Commonly found examples of electromagnetic waves include: light, microwaves, ...

Electromagnetic Interference(EMI) occurs because of a close relationship between electricity and magnetism. An electromagnetic wave consists of electric and magnetic waves running perpendicular to each other. Each component responds differently to frequency, voltage, current and distance, but with recent adv...
