I think magnetic field will be invisible in plain view (but still work), but there will be special view (like pressure).

No, I meant actually turning the magnetic field simulation off. Not just as a view, but to enable/disable the effects.

He means like how compatibility mode in the current implementation affects the heat sim. He would want something like that for magnetism sim as well, if such a thing were to be implemented. Me too.

Alright, it may will be switchable.

I too would also like to see magnetism in TPT. Would be interesting if it were combined with free moving objects
