Problem
A single circular loop of copper wire of radius 4.0cm lies flat on a horizontal bench in the gap of an electromagnet. The field at the loop is uniform, vertical and directed upwards, and its magnitude is being increased steadily from 0.10T to 0.50T. Looking down on the bench from above, is the induced current in the loop clockwise or anticlockwise? Give the reasoning.
