Bartington Instruments' HC2 Helmholtz Coil system is designed to generate stable and homogeneous magnetic fields in up to three axes. The system consists of HC2 Helmholtz Coils with a diameter of 1m, PA1 Power Amplifier and CU1 Control Unit (CU1) which interface with a PXI control system (or other compatible National Instruments acquisition card) that governs the operation of the system. Each pair of coils generates a magnetic field in one specific axis - X, Y or Z.
The coil pairs generate a homogeneous magnetic field, up to ±250μT at DC and up to ±100μT at 300Hz. The 1 metre diameter HC2 allows for testing of large items, providing a homogeneous field to 1% in a volume of 14000cm3, and homogeneous to 0.1% in a volume of 2500cm3. A mounting table is provided to hold the test item inside the central homogeneous volume.
The CU1 Control Unit interfaces between the PXI control system allowing to control the system from a Labview™-based software, whilst compensation potentiometers on the PA1 are used to cancel the local DC magnetic field.
The coil assemblies can also be purchased separately from the rest of the system.
To facilitate freight and installation, the HC2 is shipped in a flat pack form that can be assembled and disassembled at the customer’s convenience.
