Abstract
The calculation of magnetic shielding with ferromagnetic material by an eff ective reluctivity method and a time step method based on the finite elemen t calculation is investigated The calculation results of both methods are c ompared with measurement results and with each other in order to check thei r reliability and accuracy. It turns out that both methods give similar res ults for the field inside the shielding material, whereas in the surroundin g air the effective reluctivity method gives more accurate results than the present time step method.
