Split Pair Magnets

Split Pair Magnets

Scientific Magnetics are world leaders designing and manufacturing superconducting Split Pair magnets for a wide range of scientific experiments, including specialist beamline applications.

Our magnets are designed for WET and DRY operation and can be supplied as standalone units or fully integrated cryogenic systems.


  • Vertical and horizontal field direction
  • Wide optical access parallel and perpendicular to field
  • Asymmetric coil configuration for specialist applications
  • Diode protection with the option for persistent mode switch
  • Fast sweep to field High homogeneity and stability
  • Integrated HTS current leads for maximum efficiency
  • Magnet designs for UHV compatible environments

Below are just a few examples of previously manufactured systems, supplied either as standalone magnets or fully integrated WET and DRY systems.
