Magnetics
air gap
Materials science; Magnetics
The distance between the north and south poles of a magnetic circuit. In conducting pull tests this is the distance between the working surface of the magnet and the testing apparatus.
anisotropic
Materials science; Magnetics
A material that has a preferred direction of magnetic orientation which produces superior magnetic characteristics through a particular axis.
B/H curve
Materials science; Magnetics
The result of plotting the value of the magnetic field (H) that is applied against the resultant flux density (B) achieved. This curve describes the qualities of any magnetic material.
coercive force (HC)
Materials science; Magnetics
The demagnetizing force or intensity of a magnetic field, measured in Oersteds, required to reduce observed induction, B, to zero after the magnet has previously been brought to saturation.
curie temperature
Materials science; Magnetics
The temperature that a magnetic substance loses its magnetic properties.
demagnetization curve
Materials science; Magnetics
The second quadrant of the hysteresis loop, generally describing the behavior of magnetic characteristics in actual use. Also known as the B-H Curve.
demagnetization force
Materials science; Magnetics
A magnetizing force, typically in the direction opposite to the force used to magnetize it in the first place. Shock, vibration and temperature can also be demagnetizing forces.
