Magnetic field evaluation for disk conductors

A method for calculating the magnetic field from a sector or an entire disk conductor in which a radial current flows is described. New analytic expressions for the components of the magnetic vector potential and field are given in closed form. These consist of suitably polynomial, inverse trigonometric and logarithmic functions of the coordinates of the point considered and of the dimensions of the conductor, and of Legendre´s elliptic integrals of the first, second and third kind, having the same independent variables. The relations presented can be usefully adopted as efficient and time-saving algorithms in magnetic field and eddy current analysis
