Question

(Figure 1) shows a square conducting loop centered on the x axis, with its sides parallel to the y and z axes. The loop moves with constant velocity in the negative x direction toward a small bar magnet that is centered on the origin and has its polar axis aligned along the x axis.

At the instant shown, what is the direction of the magnetic force exerted on an electron sitting at the point 3, the middle of the top side of the loop? positive x direction negative x direction positive y direction negative y direction positive z direction negative z direction

Explanation / Answer

f=qvxB

v--> -x

B--> -z

therefore

f--> y
