Question

The force on the rectangular loop of wire in the magnetic
field in Figure 22.56 can be used to measure field strength.
The field is uniform, and the plane of the loop is perpendicular
to the field. (a) What is the direction of the magnetic force on
the loop? Justify the claim that the forces on the sides of the
loop are equal and opposite, independent of how much of the
loop is in the field and do not affect the net force on the loop.
(b) If a current of 5.00 A is used, what is the force per tesla on
the 20.0-cm-wide loop?
