Hello Bo,

 

Thank you for contacting us.

The MHD module also calculates the potential, which, in turn, determines another current. These two currents are then added together, so they can nearly cancel out.

Additionally, the outcome depends heavily on whether the boundary is insulated or conducting.

All these can significantly affect the force (F = J × B).

 

Best,

Nikolas
