Hi there. I would like to create a uniform magnetic field in a 3D box region of space that varies with time.

With the Maxwell Magnetostatic solver, I can use a combination of 'Tangential H-Field' and 'Zero Tangential H-Field' boundaries to create a uniform magnetic field (see

for details on how this is done). See attached image to see this:

 

However, I would like the uniform magnetic field to be time-varying, meaning I need to use the 'Magnetic-Transient' solver. I want to be able to "pulse" the magnetic field. For example:

• from 0-2ms the magnetic field is zero;
• then between 2ms-10ms the magentic field is 10A/m;
• then between 10ms-20ms the magnetic field is zero again.

Is this possible in the Maxwell Magnetic Transient Solver?

Thanks :)

Hi @hansongriggs,

I don't think it is possible to achieve. Because the field won't go to zero immediately after the source goes to zero.

May I know why you want to do that and what are you trying to achieve here?
