The magnetic moment can be defined as a vector relating the aligning torque on the object from an externally applied magnetic field to the field vector itself. The relationship is given by: where τ is the torque acting on the dipole, B is the external magnetic field, and m is the magnetic moment. This definition is based on how one could, in principle, measure the magnetic moment of an unk… WebNov 5, 2024 · The magnetic flux passing through a surface of vector area A is.
