If field reversal is required when using a a unipolar Power Supply, we offer the 5971-160 Current Reversal Switch. This Switch provides a safe way of reversing the magnets current under either manual or computer control. The USB Interface also provides control fo the Power Supply current, and readback of the Power Supply current and voltage. It will also provide field readback from a Senis Field Transducer if installed.

We take the trouble out of connecting your magnet to the power supply with a wide variety of pre-terminated cable assemblies.

For optical experiments or other applications where an axial hole in one or both poles is required, GMW can provide the poles with the hole pre-drilled to your specifications. Order part: 5503-AH - Axial hole in one pole, diameter to be specified.

Bias Coils are used for two different applications with electromagnets; obtaining a 'zero' field, or superimposing a modulated signal on the field.

For achieving a zero field, the bias coils are used with a fixed DC power supply, and set to generate a 'negative' field when the main magnet power supply is stitched off. The the main magnet power supply may then be programmed to any field from zero upwards to the magnet power supply maximum.

For field modulation, the bias coils may be used with a low power bipolar power supply such as the Kepco BOP 100-1M. Note that our magnets are of a solid yoke design, so the modulation frequency will be limited to less than 30Hz.

5485 - Bias and Modulation Coil pair.
EP030MX100-230 - DC Power Supply for 5484 Bias Coil pair, 0-30V, 1A.
