Slightly increasing the distance between the coils improves the uniformity at the coils plane but decreases it in the center. Both coils are then powered by an equal current flowing in the same direction.īy setting the distance between the two coils to the radius of the coils, R, the magnetic field uniformity in the center area between the coils is maximized but the field strength at the plane of the coils is around 7% lower. The basic set-up consists of two coils that are separated from each other by a specific distance, for circular coils this is the same as the radius of the coils. This Demonstration computes the magnetic field produced by a pair of square Helmholtz coils. A Helmholtz Coil is a set-up of coils, normally two per axis, that creates a near uniform magnetic field between them. We develop a series expansion for the calculation of the magnetic field near the center of Helmholtz coils and apply the result to a magnet of our design.
