Question

When a sheet of metal is placed in a magnetic field, which changes from zero to a maximum value, induced currents are set up in the direction shown in the diagram. What is the direction of the magnetic field.\

Professor PC Thomas Classes · Answer

Field due to induced current is opposite to the growing field. Induced current is clockwise. So the field due to induced current is into the plane of the paper. Therefore the growing field is away from the plane of the paper.\
