Finite Element Method Magnetics : PMEnergy
The energy calculated by (27) that is sourced by the coil must be the energy that is stored by the magnet, since there is no place else for the energy sourced by the coil to go. That is, W i = W m . The energy that the system stores in the magnet (or receives from the magnet, depending on the direction of change in Φ with time) is:
