Suppose the loop in Exercise 6.4 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 T s⁻¹. If the cut is joined and the loop has a resistance of 1.6Ω how much power is dissipated by the loop as heat? What is the source of this power?

A square loop of side 12 cm with its sides parallel to X and Y axes is moved with a velocity of 8 cm s⁻¹ in the positive x-direction in an environment containing a magnetic field in the positive z-direction. The field is neither uniform in space nor constant in time. It has a gradient of 10⁻³T cm⁻¹ along the negative x-direction (that is it increases by 10⁻³T cm⁻¹ as one moves in the negative x-direction), and it is decreasing in time at the rate of 10⁻³T s⁻¹. Determine the direction and magnitude of the induced current in the loop if its resistance is 4.50 mΩ..
