Magnetics

permeance (P)

Materials science; Magnetics

A measure of relative ease with which flux passes through a given material or space. It is calculated by dividing magnetic flux by magnetomotive force. Permeance is the reciprocal of reluctance.

Also called the load-line, B/H or "operating slope" of a magnet, this is the line on the Demagnetization Curve where a given magnet operates. The value depends on both the shape of the magnet, and ...

plating/coating

Materials science; Magnetics

Most neodymium magnets are plated or coated in order to protect the magnet material from corrosion. Neodymium magnets are mostly composed of neodymium, iron, and boron. The iron in the magnet will ...

polarity

Materials science; Magnetics

The characteristic of a particular pole at a particular location of a permanent magnet. Differentiates the North from the South Pole.

pole

Materials science; Magnetics

An area where the lines of magnetic flux are concentrated.

pole pieces

Materials science; Magnetics

Steel plates attached to the north and south poles of a magnet which direct the lines of flux and can control the gradient of the magnetic field.

pull force

Materials science; Magnetics

The force required to pull a magnet free from a flat steel plate using force perpendicular to the surface. The limit of the holding power of a magnet. The pull force listed is actual data acquired ...
