2)The phenomenon of generation of current in a coil whenever it is subjected to change in a magnetic field.

3)This phenomena discovered by 'Michael Faraday'

Answer 2

EMF is defined as either “Electromagnetic Field” or “Electric and Magnetic Fields”. EMF is, under either definition, a thing, an agent, or a force.

EMI is defined as “Electromagnetic Interference”. EMI is the result of an electric or magnetic field acting on a device, causing it to malfunction. It is this interference that affects the proper functioning of a device. EMI is a broad term that covers all interference from all frequencies in the electromagnetic spectrum – DC, Quasi-DC, AC and RF.
