A square-shaped loop is made of wire of diameter d. The loop is placed near a long straight wire with a current I. After the current in the long wire is turned off, the loop acquires the momentum p. What would be the momentum acquired by the loop if it were made of wire with diameter 3d, and the initial current in the long wire were 2I? In both scenarios, the shape of the loop and its initial position relative to the wire is the same.

We received relatively few solutions for our February Challenge, Mirror, mirror… and the ball! We are pleased to recognize the following successful solvers:
