Question

the magnetic moment of a current
​

Answer 1

The magnetic moment (or magnetic dipole moment) is a vector. The direction of the magnetic moment is the direction of the area of the loop as defined by the right-hand rule. ... The torque on a current loop can then be written as τ = μ × B. The magnitude of the torque is τ = μB sinθ.

Answer 2

The direction of the magnetic moment is the direction of the area of the loop as defined by the right-hand rule. ... The torque on a current loop can then be written as τ = μ × B. The magnitude of the torque is τ = μB sinθ....
