This Electromagnet System provides a unipolar field with manual or voltage programming of current. The Electromagnet has small size and low mass and can be readily mounted with any field direction. It is appropriate for laboratory or production-line measurements of magnetic separation, magneto-optic and other magnetic characteristics where a bipolar field is not required. Options are available for axial holes for light entry and exit. A bipolar power supply system is also offered.
If a bipolar system is required, please go the the Bipolar System page.
