i just want to make a 3d model of a magnet (cylindrical) showing only the magnetic flux lines. i have no problems in making the geometry. the only problem that I face is that I do not know how to assign north and south poles. is there a way or any alternative way. please let me know i am absolutely new at this. thanks in advance!

i am able to show an arrow diagram but cannot seem to direct the arrow from north to south. please help.

Hi,

you have several options under the Ampere's law node. One would be to set the constitutive relation of the magnetic field to 'magnetization' and set a suitable magnetization vector according to your needs.

If the magnet is cylindrical with symmetric magnetization you can save a lot of resources by setting up a 2D axially symmetric model instead of 3D.

Cheers
Edgar
