Helmholtz Coil HCS1HC1 Helmholtz Coil

Helmholtz Coil HCS1PA1 Power Amplifier and
CU1 Control Unit

The HCS Helmholtz Coil System generates a magnetic field of known frequency and intensity from a standard single phase AC mains supply. A mounting table is provided to hold the test item inside the homogeneity colume.

The CU1 Control Unit interfaces with a National Instruments control system, controlling the entire system through LabVIEW based PC software.
