MULTI-POLE MAGNETIC CIRCUIT COMPARISONS

MULTI-POLE MAGNETIC CIRCUIT COMPARISONS MAGNETIC CIRCUIT DESIGN SECTION 1: EXPLANATION Most permanent magnets have a direction of anisotropy, where the magnetic domains are forced into a single direction during the production of the magnetic material. The magnet must then be magnetized in the direction of anisotropy, but being one-dimensional does not mean that the location [...]

Magnet Concept

Magnet Concept Am area of the magnet, is the cross sectional areal of the magnet perpendicular to the central flux line, measured in sq.cm. at any point along its length. In design, am is usually considered the area at the neutral section of the magnet. B Magnet induction, is the magnetic field induced by a [...]
