LDJ Electronics 6007 Electromagnet Magnetometer CF Conflat Vacuum 7" Pole Cap

LDJ Electronics 6007 Electromagnet Magnetometer CF Conflat Vacuum 7" Pole Cap

The LDJ Electronics Model 6007 is a large-frame laboratory electromagnet system designed for generating precisely controlled, high-intensity magnetic fields for magnetometry, materials characterization, and physics research applications. The system pairs a substantial iron-core electromagnet — with dual coils and large-diameter pole caps — with an integrated CF Conflat-flanged vacuum assembly mounted at the top, enabling measurements on samples under vacuum conditions. The entire assembly is built into a rigid aluminum extrusion frame that houses the magnet, vacuum interface, hose and wiring routing, and a lower power/cooling module. A yellow safety warning label on the magnet housing reads "Strong Magnetic Field When Running — Personnel with Pacemakers and Medical Electronic Implants Must Stand Back Two Feet."

Applications

Electromagnet systems of this type are used in research laboratories for generating stable, variable DC magnetic fields across a precisely defined gap between the pole caps. The large 7" pole caps and 2" adjustable gap make the LDJ 6007 suitable for magnetic characterization of bulk materials, thin films, and crystals — including hysteresis loop tracing, magnetization measurements, and magneto-optical or magneto-transport experiments. The integrated CF Conflat vacuum assembly allows researchers to place samples in a controlled vacuum environment within the magnetic field, which is essential for surface-sensitive measurements and experiments requiring low-pressure conditions. LDJ Electronics, based in Troy, Michigan, was a recognized manufacturer of electromagnet and magnetometry systems for university physics departments, materials science labs, and industrial R&D environments. Systems of this class were widely used from the 1980s through the 2000s in condensed matter physics, magnetic materials research, and semiconductor characterization. The Conflat flange interface is a long-established UHV-compatible standard, meaning this system is compatible with a wide range of vacuum hardware and measurement probes.
