fig. below shows planar loops of different shapes moving out of or into a region of a magnetic field which is directed normal to the plane of the loop away from the reader. determine the direction of induced current in each loop using lenz's rule.
A coil having 100 turns and the area 0.2 m^-2 is placed normally in a magnetic field. the magnetic field changes from 0.20 Wbm^-2 to 0.60 ...
