Question

what is the conditio of electromagnetic induction ?
1. relative motion between coil of wire and galvanometer 2.relative motion between galvanometer and magnet 3.relative motion between galvanometer and generator 4.relative motion between coil of wire and magnet​

Answer 1

Answer:

I'm not sure about my answer

Explanation:

4 answer is. As the magnet spins, the magnetic field around the top and bottom of the coil constantly changes between a north and a south pole. This rotational movement of the magnetic field results in an alternating emf being induced into the coil as defined by Faraday's law of electromagnetic induction
