[FAQ]

To calculate the eddy current losses in the permanent magnet (PM) in Maxwell Transient analysis, you should do the following: 1. Set the nonzero conductivity in the material properties of a PM. 2. Activate eddy effects calculation in the PM from the menu bar Maxwell 2D / Maxwell 3D -> Excitations -> Set Eddy Effect. 3. If you are simulating in 2D, assign a zero current excitation to each magnet. (The requirement to assign a zero current excitation to each object on which the eddy effects are activated applies only to 2D. This forces the induced eddy currents to return only thru the magnet itself and not thru the background region.) 4. Apply mesh operations in order to get a very fine mesh in the PM. 5. Run simulation. 6. After the simulation is finished, you can plot solidloss (W/m3) on the permanent magnet. Also, Jvector can be plotted to see the direction of the inducted eddy currents
