Magnetic field due to currentHard
Question
Two insulated rings, one of slightly smaller diameter than the other, are suspended along their common diameter as shown. Initially the planes of the rings are mutually perpendicular. When a steady current is set up in each of them.
Options
A.The two rings rotate into a common plane
B.The inner ring oscillates about is initial position
C.The outer ring stays stationary while the inner one moves into the plane of the outer ring
D.The inner ring stays stationary while the outer one moves into the plane of the inner ring.
Solution
Both rings experience torque due to other′s magnetic field.
