Hello, I would like to simulate one orbit circle around the heart magnetic field. I had simulated a permanent magnetic field with earth value thanks to this video:

But now I want to simulate the same magnetic field but with variation in time. How can I?

If I select magnetic transient in solution type I can't create a tangential H vector around the box I create.

 

Magnetic field variation:

Tangential H is only supported in Maxwell 3D Magnetostatic and Maxwell 3D Eddy Current solvers.

So there is no possibility to have a transient of a Magnetic Field homogeneous in a box? 

If there is no possibility, could I create for example 90 different boxes with different Magnetic fields and have a transient in the movement of an object I want to check?

I found on internet this answere:

1. use the coupled field analysis. finite elements like plane53, solid97 can be coupled with the circuit element circu124. you can define the AC voltage source in the circuit. see Low-Frequency Electromagnetic Analysis Guide and Coupled-Field Analysis Guide  for details.

2. define an array and use the array as your excitation. the first row of the array is the time, the second row is the corresponding current of the specific time. see "8.4. Example: Transient Magnetic Field in a Conducting Block" in Low-Frequency Electromagnetic Analysis Guide for details.  

 

The problem is that this guide is really old and does not correspond to the actual ansys version, so can someone help me to apply there solutions to my problem and the newest veriosns? Thanks in advance.
