A rectangular wire loop (4.0 cm by 5.0 cms) has 0.20 T of external uniform magnetic field falling perpendicular to its plane. The electrical field starts decreasing at constant rate such that at t=2.0 seconds, it disappears completely. Explain why an electric current is being induced in the wire, find its value, and show its direction.
in accordance wih lenz law
flux= B.A = 0.2(0.04 *0.05)
EMF = -d(FLUX)/dt
emf induced = (0.2/2)0.0020 volts = 0.02 volts
current is clockwise direction
