8. Suppose the loop in example 2 is stationary but the current feeding the electromagnet that produces the magnetic field is gradually reduced so that the field decreases from its initial value of 0.3 T at the rate of 0.02 Ts ¹. If the cut is joined and the loop has a resistance of 1.5 , how much power is dissipated by the loop as heat? What is the source of this power?
