Q. The phenomena of electromagnetic induction is __:
Answer: induced current in a coil due to relative motion between a magnet and the coil
Notes: The phenomenon of electromagnetic induction was discovered by Michael Faraday in 1831. He discovered that moving a wire in a magnetic field generates an electric current in the wire. This phenomenon is known as electromagnetic induction and the current so produced is called induced current. It is the existence of an induced current in a circuit (such as a coil) placed in a region where the magnetic field motion changes with the time .
