All right. Now let’s consider the potential energy associated with the orientation of a magnetic dipole. Earlier we have seen that a current loop generates a magnetic field along its axis in upward direction if the current is flowing through this loop in counterclockwise direction.
Webtiny bar magnet (a magnetic dipole). We define the magnetic dipole moment to be a vector pointing out of the plane of the current loop and with a magnitude equal to the product of the current and loop area: The area vector, and thus the direction of the magnetic dipole moment, is given by a right-hand rule using the direction of the currents. z ...
