How can I calculate field strength of a Neodymium Ring magnet at an angle? I have a Neodymium Ring magnet, and I rotate the magnet around an axis perpendicular to the poles. (Not continuous rotation). For a given distance from the surface, and or for a given angle away from the center of the field, how can I calculate the field strength?
I have looked at some methods to calculate field strength, but they refer to electro-magnets, and current. Where this is a rare earth magnet, I am unsure how to perform such calculations.
The application is a device that exerts a magnetic field into a device, where either a weak, or non-existent field is not already present.
