Question

A circular loop of wire is placed in a magnetic ?eld such that the plane of the loop is
perpendicular to the magnetic ?eld. The loop is then connected to a battery and a current then
?ows through the loop. Which one of the following statements concerning this situation is true?

a) The magnetic force exerts a net
torque on the loop.
b) The magnetic force exerts a net
force on the loop.
c) The magnetic force exerts both a
net force and a net torque on the loop.
d) The magnetic ?eld has no affect on
the loop.

Explanation / Answer

because the magnetic flux is BA cos(teta) and angle between them is 0 so magnetic flux is not zero

so magnetic force do exist

so net torque also exist
