    Please help me, now I want to simulate the magnetic ring as shown in the Fig.1 under the transient field, I have a problem on the excitation coil, I don't know how to set the excitation surface. (The number of turns of the excitation coil of the magnetic ring is 200)。

Figure1. Physical picture of magnetic ring

    Now I have established the corresponding model in Maxwell. The orange area is the 200-turn excitation coil, and the gray area is the magnetic core (they correspond to Fig.2 and Fig.3).

Figure2. Excitation coil model

 

Figure3. Core model

Next, please instruct me, how should I set the excitation surface to ensure the correctness of the excitation coil?  Am I setting the excitation plane correctly in Fig.4 ? >~<

Hi Liu ShuJun,

You need to section the coil in the YZ plane, not the XZ plane.

I would like to express my sincere thanks to you, Mr. Navya C！

Now this is the correct thing to do, right ?

Appreciate for you again !

Yes,

Always section perpendicular to the current direction in the coil.

Hello ,did you solve the problem? I have the same problem. I bulit the same core and coil,and I set the excitation surface in the YZ plane . Finally, i got a error "Process '3dtds' terminated abnormally. It may have run out of memory or could have been killed by the user",but I have the enougth ram ,it is 64GB
