th magnetic field of a cylindrical magnet that has a pole

Question

th magnetic field of a cylindrical magnet that has a pole face radius 2.8 cm can b varied sinusiodally between minimum value 16.8 T and maximum value 17.2T at a frequency of 60/pie Hz.Cross-section of th magnetic field created by th magnet is downward,into th plane of th paper.At a radial distance of 2 cm from th axis find th amplitude of th electric field induced by th magnetic fied variation.kindly help,gettin no clue as to how to proceed...
