ModelMR-EM-100
Adjustable Air Gap Electromagnet
A water-cooled air-gap electromagnet on an H-frame double yoke, delivering fields up to 3 T in the gap, with both poles independently adjustable and a set of interchangeable pole caps. Built for magnetic characterization, magneto-optical and materials experiments that need a stable, repeatable field for hours at a time. Pole gap, pole caps, cooling and power options are configured to the customer's experiment, and the magnet is delivered tested with its field map.
Key features
- Fields up to 3 T at the pole gap
- Water-cooled coils rated for continuous operation at full field
- Stiff H-frame double-yoke construction for a mechanically stable magnetic circuit
- Two independently adjustable pole sides: each pole moves on its own hand wheel with a position scale, so the gap can be set symmetrically or offset and returned to the same setting
- Interchangeable pole caps in three diameters, Ø100 mm flat for the most uniform field over large samples, Ø75 mm tapered for general high-field work and Ø50 mm tapered for the maximum field, exchanged in minutes without tools
- Top and side access to the gap for sample rods, Hall probes, optical paths and cryostat or oven inserts
- Bipolar operation with a matched power supply sweeping continuously through zero
- Thermal and water-flow interlocks, lifting eye and slotted mounting base
Ideal for
Magnetic characterization and magnetometry setups, magneto-optical Kerr effect and Faraday measurements, Hall-effect and magnetoresistance studies, magnetic actuation and soft-robotics experiments, materials and physics teaching laboratories.
Options
Pole-cap set (Ø100, Ø75, Ø50 mm or custom), maximum field, bipolar power supply and chiller package, gaussmeter with Hall probe, control software, cryostat or oven access, custom base and mounting.
