Heya...
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off.
Electromagnetic waves: According to Maxwell "electromagnetic waves are those waves in which there are sinusoidal vibration of electric field and magnetic field vectors at right angles to each other as well as right angles to the direction of wave propagation."
Faraday's law of electromagnetic induction:
Faraday's law states that any change in the magnetic field of a coil of wire will cause an emf to be induced in the coil. This emf induced is called induced emf and if the conductor circuit is closed, the current will also circulate through the circuit and this current is called induced current.
