(a) Magnetic field lines of a magnetic dipole (b) Magnitude of the magnetic dipole field in the direction of ↑ B₀. The values along the magic angle (${\displaystyle \mathrm{\Theta }={\text{54.7}}^{\circ }}$) are zero and there are lobes of positive and negative field strength, indicated as areas of relative hyper- and hypointensity respectively.
