SHC3D - 3D Helmholtz Coil System

The SHC3D is a Helmholtz system with three orthogonal arranged coil pairs, which enables generation of three-dimensional magnetic field vectors. The SHC3D was designed for calibration of weak field sensor application.

The SHC3D will be shipped in different coil configurations, tested and matched for equal coil resistance, or the polycarbonate frame only without the coils.
