PHYS208 Fundamentals of Physics II

Hint for Ch. 31, 21P

Assign a directed area vector to the loop to determine the total change in magnetic flux when the loop is flipped. Also note that the axis of the coil is at 20 degrees, not 70 degrees, from the magnetic field of the Earth.

Thanks to Andrew Towle and Jim Durbano for reporting a typographical error previously in this hint.
