WebUnits of moment. From the formula for the size of the moment, we see that the appropriate units of measuring moments are Nm (newton-metres). A force of 1 N at a perpendicular distance to a pivot of 1 m exerts a moment size of 1 Nm. One Nm is the same as one J (joule), which is a unit of energy. Thus, moments have the same units as energy.
Definition 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: $${\displaystyle {\boldsymbol {\tau }}=\mathbf {m} \times \mathbf {B} }$$ where τ is the torque acting on the dipole, … See more In electromagnetism, the magnetic moment is the magnetic strength and orientation of a magnet or other object that produces a magnetic field.
