Answer:45 V

Explanation:Electromagnetic induction occurs when there an electromotive force is induced in a coil due to a change in magnetic flux through the coil.

Mathematically, the induced voltage is given by Faraday-Newmann-Lenz law:

where

N is the number of turns in the coil

is the change in magnetic flux

is the time elapsed

In this problem,

N = 6 is the number of turns in the coil

The change in magnetic flux is:

is the time elapsed

Substituting, we find the induced voltage:

And the negative sign only indicates the direction.
