PERMANENT MAGNET OPTIONS FOR MAGNETIC DETECTION AND SEPARATION - RING MAGNETS WITH A CONCENTRIC SHIM

摘要

Permanent magnet assemblies include a central cylindrical magnet having a bore. The cylindrical magnet is magnetized along a selected radial direction and is enclosed within a ferromagnetic shim. A uniform magnetic field, field gradient, or other field distribution can be produced in the bore based on the bore cross-sectional shape.
