Halbach Array Mandhala Polar Define magnetization directions

Please login with a confirmed email address before reporting spam

have a nice day. my name is Erhan. I want to model the 8-magnet double-sided halbach mandhala array. In physics, I chose 'magnetic field no curret'. I'd like to identify a neodymium magnet. I'm entering Br values. As it is known in the Halbach series, there must be 2 magnets opposite each other. One is N pole and the other is S pole. I don't know how to determine the polarity and magnetization directions. My joy if you help.

Erhan,

Use cylindrical coordinate system to define opposite magnetization, as shown in the Application Library example:
