Field and flux of a magnetic dipole. The magnetic field at a point M(r, θ) distant from a magnetic dipole m is expressed as B(M) = − µ0 4π ∇ m · r r 3  This formula is identical to that of the electric field produced by an electric dipole moment m, after changing µ0 into 1/0. q m i z r ur uq O O’ M a R’ We consider a small planar and circular loop of center O, radius a, carrying a current i and we use a spherical coordinate system (r, θ, ϕ) with the z-axis oriented along the magnetic dipole moment: m = muz. The expression of the gradient in spherical coordinates is as follow: ∇φ = ∂φ ∂r ur + 1 r ∂φ ∂θ uθ + 1 r sin θ ∂φ ∂ϕuϕ a. Express the corresponding magnetic dipole moment as a function of a and i.
