A flat square coil with N = 5 turns measures 2.0 m on each side. The coil lies stationary in a uniform magnetic field. The magnetic field has a magnitude of 0.25 T and is directed into the page, perpendicular to the plane of the loop.
The coil has a total resistance of 0.5 ohms. If the magnetic field is reduced steadily from 0.25 T to 0.10 T in 0.3 seconds, what is the induced current in the loop while the change is taking place?
Next problem : F - Refraction with two media.
