WebMar 5, 2024 · The SI unit for magnetic moment is clearly N m T − 1. If an electric current I flows in a plane coil of area A (recall that area is a vector quantity – hence the boldface), the torque it will experience in a magnetic field is given by. (17.2.2) τ = I A × B. This means that the magnetic moment of the coil is given by. (17.2.3) p = I A.
