If the magnetic flux linking all the turns of a 50 turn coil changes from 10mWb to 20mWb and induces an emf of 62.5V in the coil, calculate the time over which the flux changes.

2. Relevant equations

e=Nd x change in flux / dt

3. The attempt at a solution

Not sure if this is correct formula but transposed formula to:

t = Number of turns x Change in flux / e

= 50 x 10 / 62.5

t = 8s
