A permanent magnet has a magnetic moment $m$ associated with it. When exposed to a magnetic field $B$ the torque acting on the magnet can be calculated as $\tau = m \times B$.
I am trying to calculate the torque imposed on a disc magnet in a magnetic field with a known strength. However, I do not know the magnetic moment of the magnet. How can the magnetic moment of a permanent be calculated?
So far I have the datasheet (link) of the magnet I would like to use which contains the following magnetic properties: Magnetisation Grade, Residual magnetism, Coercive field strength bHc, Coercive field strength iHc and the energy product. However, I cannot seem to find the magnetic moment using these properties.
Any suggestions or hints?
