The Helmholtz coil with an outer diameter of 1.0 meters has been successfully delivered

Recently, our company successfully installed and delivered an electromagnetic field system designed for a national laboratory.

Helmholtz coil

The maximum outer diameter is 1.0 meter, the overall material is non-magnetic, and the base is fixed with aluminum profiles. The coil can be directly placed on the ground, and the coil position can be locked after adjusting the coil spacing. The magnetic field strength can reach 50 Gauss, water-cooled, and two coils are placed in series. The weight of a single coil is 110KG, and the uniformity of the central area is better than 0.6%.
