A square loop can freely spin about one of its horizontal
segments, see the picture below. The loop is placed in a vertical
uniform magnetic field of magnitude B = 0.1 T. Find
the current in the loop if it makes an angle of 10° relative to the
vertical (the line of magnetic field). The mass of the loop
m = 25 g and the size of the loop
a = 14 cm.
