Magnetic moment via current and contour area

The magnetic moment is the main physical quantity characterizing the magnetic properties of a substance, that is, the ability to create and perceive a magnetic field.

Conditions:

  1. Ideally, the conductor itself should be infinitely thin. But a conductor can have any shape and size if its dimensions can be neglected relative to the size of the closed circuit that it forms.

  2. The plane must be flat for this formula to be applicable, and the current must only make one turn around the contour.
