Question

A wire in the shape of an "M" lies in the plane of the paper. It carries a current of 2.0 A, flowing from points A to E, as shown in the figure. It is placed in a uniform magnetic field of 0.75 T in the same plane, directed as shown on the right side of the figure. The figure indicates the dimensions of the wire.

My question is What is the magnitude of force acting on AB this wilre?

A wire in the shape of an M lies in the plane of the paper. It carries a current of 2.0 A, flowing from points A to E, as shown in the figure. It is placed in a uniform magnetic field of 0.75 T in the same plane, directed as shown on the right side of the figure. The figure indicates the dimensions of the wire. f= B I L sin theta is not correct. can you tell me why? My question is What is the magnitude of force acting on AB this wilre?

Explanation / Answer

for on AB = 0.10606 N away from plane

on BC = 0 N

on cD =0.09N away from plane

on DE = 0.10606 N opposite to force on AB

so net force =

0.09N away from plane
