3D Model of "Voltage Induced in a Coil by a Moving Magnet"

Hi

I wanted to do the 3D version of the Model "Voltage Induced in a Coil by a Moving Magnet" which is in the Comsol Library.

I used the same physics, materials and boundary conditions, but unfortunately the 3D Model does not converge.

Do I have to adapt something in order to make the 3D model work??

I would be really glad if you can help me out!!!

Thanks
