Question

The two diagrams to the top convey a current on a wire oriented perpendicular and into the paper. In the top diagram, the current goes through the center of a circular loop. In the bottom diagram, the current goes through the center of a circular arc, but the loop has a straight wire shorting across its base. You can assume the wire cuts across the arc symmetrically, so that the current i is directly above its center.


Assume each loop has a current flowing clockwise:


a) 1.What is the direction of the force or torque on the loop in the top diagram?


b) 2.What is the direction of the force or torque on loop in the bottom diagram?

Explanation / Answer

a) force = 0 torque = 0 b) force = out of the page
