Franklin Jackson · Answer 1

TRUE

Explanation:According to Faraday's equation, the induced emf is directly proportional to the rate of change of magnetic flux.

EMF=-NΔΦΔt, where N is number of turns of wire round the coil, ΔΦ rate of change of magnetic flux and t is the time measured in seconds.

Magnetic flux is affected by the field strength and the area covered by the coil, if magnetic field increases the induced electromotive force will increase.
