A square loop of side 12 cm with its sides parallel to X and Y axes is moved with a velocity of 8 cm 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 along the negative x-direction (that is it increases by as one moves in the negative x-direction), and it is decreasing in time at the rate of Determine the direction and magnitude of the induced current in the loop if its resistance is 4.50 mΩ.

Q1
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 . If the cut is joined and the loop has a resistance of 1.6 Ω, how much power is dissipated by the loop as heat? What is the source of this power?
Q2
A square loop of side 12 cm with its sides parallel to X and Y axes is moved with a velocity of 8 cm 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 along the negative x-direction (that is it increases by as one moves in the negative x-direction), and it is decreasing in time at the rate of Determine the direction and magnitude of the induced current in the loop if its resistance is 4.50 mΩ.
Q3
It is desired to measure the magnitude of field between the poles of a powerful loud speaker magnet. A small flat search coil of area 2 with 25 closely wound turns, is positioned normal to the field direction, and then quickly snatched out of the field region. Equivalently, one can give it a quick 90° turn to bring its plane parallel to the field direction). The total charge flown in the coil (measured by a ballistic galvanometer connected to coil) is 7.5 mC. The combined resistance of the coil and the galvanometer is 0.50 Ω. Estimate the field strength of magnet.

(a) Suppose K is open and the rod is moved with a speed of in the direction shown. Give the polarity and magnitude of the induced emf.
(b) Is there an excess charge built up at the ends of the rods when
K is open? What if K is closed?
(c) With K open and the rod moving uniformly, there is no net
force on the electrons in the rod PQ even though they do experience magnetic force due to the motion of the rod. Explain.

(e) How much power is required (by an external agent) to keep
the rod moving at the same speed ( ) when K is closed?
How much power is required when K is open?
(f ) How much power is dissipated as heat in the closed circuit?
What is the source of this power?
