Rare Earth

Is the electrical potential of a rare earth magnet measured by the mass of the magnet?

Is there a formula to calculate this potential? Thank you for any help you can share.

Magnets don't have electrical potential. They're magnets, not batteries.

If you're talking about the work function of a metal, it's unique to each metal and doesn't depend on the mass of the lump or whether it's a magnet.
