Question

Consider two identical circular loops of radius a, separated by a distance a, with the second (right hand) coil rotated slightly clockwise relative to the first when looking from above as shown in figure (a)

A large current is suddenly injected into the left hand loop. What happen to the right hand loop?

Can't tell without knowing which direction current injected into left loop

Force to the left, torque rotates clockwise (in top view)

Force to the right, torque rotates clockwise (in top view)

Force to the right, torque rotates counterclockwise (in top view)
