I am using a Magnet like this in an assembly and I am trying to calculate the torque in point P2 (see picture below) resulting from the attraction force F between my magnet and the steel part.
As I assume that the magnetic force is a volumetric one, I am not sure which distance to point P2 to take for my torque calculation.
In the case of an equidistant gap (no tilting) between the rotational symmetric Aluminium part which is carrying the magnet and the Steel part, I think the resulting Force can be seen as it is applied in the center of the magnet which is in a distance of L1 to P2?
Therefore, in this case the resulting torque around P2 would be: M=F*L1. Please correct me if I'm wrong.
But in the case of tilting I am not sure which distance (L2 or LP) to consider for torque calculation. As P1 is the only contact point between the two parts it might be the point where the load on the steel plate is applied?
Thanks for your help!
