I have a magnetic dipole moment of a known magnitude and direction (which I calculated). I need to find out what the magnetic field is at a point p away from my loop. This point is exactly perpendicular my loop. I have a formula here that says B(p) = (permeability constant * magnetic dipole moment) / (2pi * p^3). However this formula was derived by assuming my coil is a circular loop. My loop is a square. Can I still use the same formula? Thx for any help.
