Magnetic field inside diametrically magnetized ring magnet

[Chris Fuccillo]

Could anyone point me to the proper formula to calculate the magnetic field strength in the gap/hole(ID) of a diametrically magnatized ring magnet.

I'm not sure if this magnetic field has the direction you are interested in, but here is a previous PF thread that might be helpful: https://www.physicsforums.com/threa...ed-permanent-ring-magnet.867355/#post-5445294

Thank you. That is a good example for an axial magnatised ring magnet. It may calculate the same but that is why I was looking for a diametrically magnatized example
