Helmholtz Coil System

3-dimensional Helmholtz coil system to generate custom magnetic fields

The Helmholtz Coil System is a set of six copper coils that, through the control of their electrical current, generate a constant magnetic field. This system includes a load surface with an air-bearing interface that fastens the subsystems/devices under test. The equipment is used during testing and calibration activities for various subsystems and devices of a spacecraft's attitude control system.
