Question
A conducting loop is made
in the form of two squares
of sides s1 = 2.5cm and s2
= 5.1 cm as shown. At time
t = 0, the loop enters a
region of length L = 15.1
cm that contains a uniform
magnetic field B = 1.5 T,
directed in the positive z-
direction. The loop continues through the region with constant speed v =
40 cm/s. The resistance of the loop is R = 2.6 Q.
