Induced current in a conductor under a magnetic pulse

[LJ8551]

Dear Elmer group,

I would like to calculate the induced current in a conductor under a strong magnetic pulse (0 to 30T in 5 ms).
I tried to use the Magnetic Induction Equation via MagneticSolver (with velocity=0) on a simple copper disk.
The magnetic pulse field is applied belong the z axis which corresponds to the disk axis but the calculated current is almost zero.(should be concentric current loops)
Please find attached the mesh I used and the sif file.

The equation to be solved is : rot E = -dB/dt and then calculate J=sigma E.

Could you please tell me if I can use Elmer to solve that kind of problem ?

best regards
LJ
