I did.
The results are correct .
Some said it is due to the fact that in the center of the ring there is very little field flux, which make sense . The center Z axis is very much away from the actual magnet.
So far what I came up with is using a block magnet formula to calculate a ring...
Hi Everyone ,
Can anyone explain why I am getting negative result with a large Neodymium N35 ring Magnet ?
Br: Remanence field, independent of the magnet's geometry
z: Distance from a pole face on the symmetry axis
D: Thickness (or height) of the ring
Ra: Outside radius of the ring
Ri...
