A circular loop of radius 5.0 cm and resistance 0.20 Ω is placed in a uniform magnetic field perpendicular to the plane of the coil. The magnitude of the field changes with time according to B(t) = 0.50e−0.20t T, in which t is in seconds. What is the magnitude of the current induced in the coil at the time t = 2.0 s?
