25 s that the magnetic field drops from 1.6 T to 0 T?E = N*A*(dB/dt) = 209 * 0.25m^2 * (1.6 - 0)T / 0.25s = 334.......
A coild with 209 turns of wire, a total resistance of 26 Ω, and a cross sectional area of 0.25 m2 is positioned with its plane perpendicular to the field of a powerful electromagnet. What average current is induced in the coil during the 0.25 s that the magnetic field drops from 1.6 T to 0 T?

-
The average emf induced in the coil is
E = N*A*(dB/dt) = 209 * 0.25m^2 * (1.6 - 0)T / 0.25s = 334.4 V

The average current in the coil is
I = E / R = 334.4V / 26 Ω = 12.86 Amps
