A circular coil 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)=(0.50 T)e−20t,{“version”:”1.1″,”math”:”B(t) = (0.50~\text{T}) e^{ -20t},”} where t is in seconds. What is the magnitude of the current induced in the coil at the time t = 2.0 s?
