# Magnetic Moment of a Rare-Earth Magnet?

fasc
I was trying to find the value of the magnetic field at a distance x from a rare-earth magnet and came across this equation:

$B=\mu_o*2\mu/(4\pi*d^3)$

Does anyone happen to know the magnetic moment, $\mu$, of a rare-earth magnet? Nothing specific, an order of magnitude value is fine.

Thank you!
