Uniform Magnetic field?
Hi everyone, I am wondering how I can generate a uniform magnetic field in Comsol. Basically, I want to simulate a metal particle moving in this uniform field. Now I am thinking put all the particles...

Hi can you not try out by going to the physics settings of your surrounding subdoman and in the "constitutive relation" select either B=mu0*mur*H+Br or B=mu0*H+mu0*M and define a Br or a M in the...

Define the space where your particles will move (e.g. a cube in 3D) and specify the field intensity at the boundaries, that way you don't need to worry about the field sources .

Setting the field at all boundaries works for creating a uniform field region once you realize that the "Magnetic Field" boundary condition specifies the "tangential" component of the field in absolute...

Hi, I am using comsol 4.2a. I am trying to simulate the hartmann flow problem. I have two parallel plates and a conducting liquid is flowing through it, in the presence of uniform constant magnetic...

Hi There are several options, but first of all so you really need MEF and solving for V ? (haven't checked the application though) as its far heavier than MF and often MF is enough at least to debug...

Hi Ivar, The method to apply magnetic field is very effective and common in the comsol module cases. I tried to use this method before but the results cannot give me the UNIFORM magnetic field. If I...

Hi Juan, I use the method exactly the same with your description. But the magnetic insulation will be overridden, to correct that, I build a bigger sphere outside and force the magnetic insulation...

Hi Chris, Good to know that, thank you very much for this trick.:) But I have one more question. If I apply my uniform magnetic on the boundary as the "Magnetic field boundary condition" then I will...

Hi Mithlesh, Did you get what you expected? I am also doing the simulation of Hartmannn flow by comsol but I am not sure whether the way I apply the uniform magnetic field is correct or wrong. I...
