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.

GMW Offers a range of Pole Caps for the 3473 Electromagnet from 25mm to 150mm. Order by part numbers as listed below:

17801355 - Single Pole Cap, 25mm.
17801354 - Single Pole Cap, 50mm.

Pole Spacers

Higher field uniformity may be achieved with a set of precision ground pole spacers. These spacers come three to a set and include a delrin spacer ring assembly to accurately locate the spacers. This ring assembly may be machined to hold experiment fixtures, and may even include a set of Bias Coils.

11900400 - Spacer Assemby, for 100mm poles.
11900410 - Spacer Assemby, for 100mm poles, with bias coils.
11900420 - Spacer Assemby, for 150mm poles.
11900430 - Spacer Assemby, for 150mm poles, with bias coils.

Bias Coils

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 100-1D. Note that our magnets are of a solid yoke design, so the modulation frequency will be limited to less than 30Hz.

5484 - Bias and Modulation Coil pair.
11900202 - Drawing of a single coil for the 5484 Bias Coil pair.
EP030MX100-230 - DC Power Supply for 5484 Bias Coil pair, 0-30V, 1A.
