demagnetization curve
demagnetization curve
[dē‚mag·nə·tə′zā·shən ‚kərv] (electromagnetism)
Graph of magnetic induction B versus magnetic field H in a ferromagnetic material, as the magnetic field is reduced to 0 from its saturation value.

Also, the magnetization of the magnet is assumed as a linear second quadrant
demagnetization curve [4-6] of the form: [B.sub.m] = [B.sub.r] + [micro.sub.m][H.sub.m] and [micro.sub.m] = [B.sub.r]/[H.sub.c] ; where [B.sub.r] is remanence of magnet, [H.sub.c] coercivity and [micro.sub.m] permeability of magnet.
The
demagnetization curve of Nd-Fe-B rare-earth permanent magnet is a straight line.
PerMag covers all aspects ofmagnetostatics, including saturation effects in soft materials and permanent magnets with non--linear
demagnetization curves. The package includes Mesh, an automatic conformal mesh generator with a built-in drawing editor and DXF import capability.
