Anyone know the origin of the equation in ACDC/permeable_sphere_static_bfield?

the (1) eqaution which calculates the flux density inside a permeable sphere
B=B0*(3*mu_r/(mu_r+2));
where the B0 is the background magnetic field, the B is the flux density inside the permeable sphere.
The simulation agrees with this analytic formulation, but I wonder the origin derivation of this formulation or where I can find some more details about the formulaiton.
Can anyone do me a favor?
