🐞 Description of the bug

When creating the region of the magnet with RegionMagnet() we are expecting to have the parameter br_value=1 so that if one wants to change it to further do it with br_multiplier. Even if we don't set a magnet material. In the below example a magnet material is also used. Currently, if the br_value=0 we cannot set successfully a multiplier. Else, we could further have a set function as set_br_value to manually set the value.
