Custom Electromagnets

For over 60 years, Arnold has manufactured custom electromagnets made of thin-gauge copper or aluminum foils, and wire wound as well. The electromagnet, or solenoid, provides flexibility in generating magnetic fields so they are desirable for klystron, TWT, ion implantation, chemical etching, chemical dispersion, MRI and other wave guide applications.

Arnold manufactures a wide variety of custom electromagnets which generate uniform or proportioned magnetic field shapes and with a wide range of magnetic field intensities. These electromagnets are either made up of tape wound foil wafers or built up from coils of wire.

In tape wound electromagnets, each wafer is electrically controlled to the precise field strength desired. The magnetic field distribution may be uniform, or it may have peaks, plateaus and valleys along the axial length of the electromagnet as dictated by your requirement. When a specific field shape is desired, the shaped field electromagnet can be designed to that configuration with great precision. Wafers may be of various widths within the electromagnet design and they can be made interchangeable. Nominal I.D. and O.D. may be selected to meet application size requirements.

Special designs are available which utilize chilled oil or liquid nitrogen to allow higher than normal current, generating up to 200% greater field intensity than an uncooled design.
