Magnetics
pull test
Materials science; Magnetics
A test of holding value or breakaway force and reachout, usually conducted with a flat ferrous plate or ferrous sphere and a spring scale.
rare earth
Materials science; Magnetics
Commonly used to describe high energy magnet material such as NdFeB (Neodymium-Iron-Boron) and SmCo (Samarium-Cobalt).
reach out
Materials science; Magnetics
The distance in which a magnetic field will extend from the magnet source.
relative permeability
Materials science; Magnetics
The ratio of permeability of a medium to that of a vacuum. In the C.G.S. system, the permeability is equal to 1 in a vacuum by definition. The permeability of air is also for all practical purposes ...
reluctance
Materials science; Magnetics
A measure of the relative resistance of a material to the passage of flux. It is calculated by dividing magnetomotive force by magnetic flux. Reluctance is the reciprocal of permeance.
remanence
Materials science; Magnetics
The magnetic induction that remains in a magnetic circuit after the removal of an applied magnetizing force. Remanence has the symbol (B d ).
residual flux density
Materials science; Magnetics
It is the magnetic induction remaining in a saturated magnetic material after the magnetizing field has been removed. This is the point at which the hysteresis loop crosses the B axis at zero ...
