Electromagnet in 3D

Hi!!

I am a new user to comsol and electromagnetics domain.

As a first step, I scanned through the models in model library in order to find the required modules for my geometry.
I' ve sorted out much of that and drew a basic geometry.In the following step I need to model an electromagnet in 3D.
I tried to search in the model library but none of the models clearly explain as to how to model an electromagnet in 3D.May be I am missing something.

so,anybody here could suggest me any suitable example in model library than can be helpful to model an electromagnet in 3D.If not available,then can you please provid me some basic stepd of modelling an electromagnet in 3D.I am using Comsol 3.5.


Thanks in advance
Kind regards.
