HC2 1m Helmholtz Coils

HC2 3-axis 1 metre Helmholtz Coil Assembly

Helmholtz Coil systems | HC2

Bartington Instruments' Helmholtz Coil systems consist of an assemblies of up to three pairs of coils designed to provide stable homogeneous magnetic fields. The HC2 system has a diameter of 1m, a drive amplifier (PA1) that runs from a standard mains socket, and a control unit (CU1) to interface with the PXI control system 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 of volume 14000cm with < 1% error, or 2500cm with < 0.1% error. A mounting table is provided to hold the test item inside the homogeneity volume.

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.

The CU1 control unit allows the user to set the field, set any DC compensation as required and receive feedback from the Helmholtz Coil. It can include a National Instruments™ PXI system that operates using LabVIEW™-based software.

Typical applications:

  • Calibration of three-axis magnetic field sensors
  • Creation of a known magnetic environment
