Consider a circular loop of wire with a mass m, radius R, and a
steady current I. The loop is vertical such that the
gravitational force on the loop points straight downwards. You may
assume this is near the surface of the earth so the
force of gravity has a magnitude of |~FG|= mg. The upper half of
the wire (the region above the dashed line) is immersed
in a uniform magnetic field with magnitude B and points into the
screen (as indicated by the x’s in the figure). Below
the dashed line the magnetic field is zero.
a) If the net force on the loop is zero determine the value of the
current I and the direction the current should flow
(clockwise or counterclockwise in the plane of the screen).
b) What is the torque around the center of the loop due to the
magnetic force?
