Torque: A flat circular wire loop lies in a horizontal plane on a table and carries current in a counterclockwise direction when viewed from above. At this point, the earth's magnetic field points to the north and dips below the horizontal. Which side of the coil tends to lift off of the table due to the magnetic torque on the loop?
A. the north side
B. the east side
C. the south side
D. the west side
E. The entire loop lifts straight up.
