Please help me on how to give an excitation in a circular coil. I have taken one section and given excitation on it. But the flux density plot is not uniformly disributed. May be the reason is that current is not circulating. Please clarify my doubt and help me. Thanks.

Hi Janardan Kundu,

Your excitation is correct. I think you should increase the region size to a large proportion.
Please refer to the below posts
Why simulated currents inside a magnetic shield in 3D don’t match 2D (cylindrical around z) results? (ansys.com)

Changing the boundary region paddings in Maxwell changes the results? (ansys.com)

Thank you. The excitation problem is solved. But when I am converting 3D to 2D the results don't match? Could you tell me if the symmetricity lost? Should I provide a model depth (e.g., 2*pi*r) in 2D design setting or any other process such that I can convert the 2D to 3D (circular) again.
