Question

Why is a current loop considered a magnetic dipole?

Answer 1

When current flows in a loop and is suspended freely it stays along north-south direction,. So it behaved as a magnetic dipole of magnetic moment 'm' amp-m2. The rule of assigning polarity is that if the direction of current on flowing through the nearer face is clockwise, the face is south pole and if anticlockwise, the face is north pole.
