Asingle loop of aluminum wire, lying flat in a plane, has an area of 8.40 cm2 and a resistance of 2.40 ω. a uniform magnetic field points perpendicular to the plane of the loop. the field initially has a magnitude of 0.500 t, and the magnitude increases linearly to 3.00 t in a time of 1.08 s. what is the induced current (in ma) in the loop of wire over this time?
