Transient Magnetic region: about
What we can simulate?
By using regions it is possible to describe:
-  material media such as:- comprising of air or vacuum (permeability μr =1)
- magnetic media (permeability μr)
- 
                     magnetic or non-magnetic (permeability μr) and conducting (resistivity ρ) 
- coils (with uniform density of current)
 
-  boundary conditions of the following types:- normal electrical field (on faces)
- tangent electrical field (on faces)
