A single-turn rectangular coil, whose length is 5 cm and width is 2 cm, has a resistance of 2 Ω. The magnetic field at all points inside the coil, in a direction parallel to the plane of the rectangular coil, varies according to B = Boe-a1, where Bo = 0.25 T and a = 200 Hz. What is the current induced in the coil at t = 0.001 s?
