An electric field exists between a pair of circular metal plates measuring 3.00 m in radius. The field is uniform across the surface of the
plates but increases in strength at a rate given by E(t) = At², starting at t = 0 and persisting for 33.0 seconds. The constant, A, has a
value of 69900 V.m¹.s². How strong will the magnetic field be on the edge of the plates at the end of the 33.0 second interval?
