Question

Find the force on each segment of the loop below. The current in the circuit, moving in the direction of the arrows, is 2.00 A. There is a uniform magnetic field of magnitude 0.300 T pointing to the right in the plane of the paper. What will happen to the loop?

Explanation / Answer

Note that

F = B I L   [if the wire is perpendicular to the field]

where the direction is determined by the right hand rule.

Side on the left:

F = 0.042 N, into the page

The top and bottom sides:

They experience 0 FORCE as they are parallel to the field.

For the side on the right:

F = 0.042 N, out of thepage

***************************

The loop will turn, with the right side going to the left.
