Power Supplies and Current Reversal

We offer several different power supplies for the 3472 electromagnet; the Amtek switch mode, and the Danfysik high stability linear.

The Amtek switch mode power supplies feature a stability of 0.05% over 8 hours and they are available with an optional IEEE-488 interface. Order part numbers:

5971
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.

Magnet Current Cables

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:
3473-AH - Axial hole in one pole, diameter to be specified.

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.

11900460-50 - Spacer Assemby, 50mm gap, for 200mm poles.

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 aplitude and frequency will be limited by eddy currents.
