Hi guys! I recently saw on Wiki that given a magnetic potential A(r)=(u/4π)(mXR/r^3) ,( where u is the permeability of free space, m is the magnetic dipole moment of a magnetic field, R is the position vector, and r is the distance from the magnetic field ) upon taking the curl of the magnetic potential A(r), one obtains (u/4π)([3(m•r)R/r^5]-[m/r^3]). Can someone show me how they ended up with this result? I would like a step by step process please.(: the wiki article is called Magnetic Moment under the section called Effects of an External Magnetic Field on a Magnetic Moment.
