Magnetic field of ferromagnetic material

  • #1

Main Question or Discussion Point

I've searched high and low among the vast archives of the internet and have yet to find any kind of formula regarding the magnetic field strength of ferromagnetic material (i.e bar magnet... etc). Does anyone know what/if there is one? As is B(r)=....?
Thanks

It really depends on (1) how strong the field used to create it was and (2) the magnetic susceptibility of the ferromagnetic material.

If you don't know those things, you can always get a Hall effect meter and measure the field at the point that you care about it. Or, if you really want to get hands-on, heat the magnet above the Curie point and induce a field yourself.
