The figure below shows a rectangular loop that has a resistance of 2.0 Q, a length of 5.0 cm,
and a width of 2.0 cm (Conversion Factor: 1 m = 100 cm). The magnetic field at all points inside
the loop is into the page, and its strength varies according to B = Boeat, where Bo = 0.25 T
and a = 200Hz. What is the current induced in the loop at
a) t = 0.001 sec. Answer: I = 0.020 A, in the clockwise direction.
b) t = 0.002 sec. Answer: I = 0.017 A, in the clockwise direction.
c) t = 0.01 sec. Answer: I = 0.0034 A, in the clockwise direction.
