Magnetic field of coil

Thu, 12 Apr 2012 17:29:41 +0000

Hi,
I am new in Comsol and need simulate magnetic field of two loops of coil, between is a block of material with permittivity 60. I have done the model, choose materials of it, but I dont know, how to display a plot of magnetic field strenght and direction. Can anybody help me?

Coil in Femlab 3.1

Fri, 21 Oct 2011 12:58:51 +0000

Hi,
I use elder Femlab 3.1 and would need to simulate a coil. How can I do it there? I have searched any documentation but no succes. And the files in this forum are .mph and Femlab 3.1 uses still .fl
If I have also a ring and suppose this is my "coil", how can I introduce the current on it? Where can I find it? I was used to model fluids and this is my first attempt in electromagnetics...
Thank you for any help!

Electromagnet

Hello,

I would like some advice on the best way to approach this problem. I have tried and tried with various different physics types and boundary conditions:

I am modeling an electromagnet, with the end goal of solving for the electric and magnetic field due to the electromagnet. I have created a geometry with a helix (the current carrying coil) and an iron core. What I would like to do is specify a current flowing through the wire coil and vary that parametrically to see the variation in B and E field strength.

I will eventually place this model in an air-filled box to see how the field propagates in air.

The model I have attached is just the geometry with no physics attached to it, because I'm not sure which the most appropriate. I presume that 'magnetic and electric fields' is the way to go because those are the two quantities I would like to measure but I could be wrong.

Help is greatly appreciated.
Kind Regards,

Dominic.
