GMW Dipole Electromagnets (Cu)

These versatile, variable-field Electromagnets are suitable for sample magnetization, magnetic separation, precision sensor calibration, Hall effect studies, magneto-optics, ferromagnetic resonance, B-H curves and EPR/NMR spectroscopy. The C-Frame and H-Frame Electromagnets have changeable Pole Caps, and most have adjustable Pole gaps to enable optimization of the geometry and field to a specific application.

All of these Electromagnets have iron Yokes and the Poles increase the maximum magnetic field with a given Coil power. The Yoke also provides self shielding to minimize the external fringe magnetize fields. For high magnetic field ramp makes some of these designs can be offered with laminated Yokes and Poles, see 5403AC as an example.
