Excessive bending, incorrect heat treatment, or even rough handling can adversely affect electrical steel's magnetic properties and may also increase noise due to magnetostriction.
32.
The alloy has the highest magnetostriction of any alloy, up to 0.002 m / m at saturation; it expands and contracts in a magnetic field.
33.
It is a " soft " magnetic material; it has low magnetic anisotropy and magnetostriction, giving it a low coercivity so that it saturates at low magnetic fields.
34.
The low magnetostriction is critical for industrial applications, allowing it to be used in thin films where variable stresses would otherwise cause a ruinously large variation in magnetic properties.
35.
Additionally, a non-zero piezomagnetic moment can be produced by mechanical strain " alone ", at zero field-this is not true of magnetostriction.
36.
Research interests extend to high-temperature superconductivity, magnetic phenomena such as magnetic resonance, magnetostriction, and magnetooptics, as well as optical and magnetic phenomena in semimagnetic semiconductors.
37.
After graduating with a degree in physics in 1887, Nagaoka worked with a visiting Scottish physicist, Cargill Gilston Knott, on early problems in magnetism, namely magnetostriction in liquid nickel.
38.
While he used many different experimental techniques over his career, including neutron scattering, magnetostriction was a technique that Fawcett especially developed as an effective probe of magnetism in metals and alloys.
39.
Ferromagnetic materials, such as iron, nickel, and cobalt, exhibit a characteristic called magnetostriction, where the Young's modulus of the material is dependent on magnetic field strength.
40.
Magnetostriction headphones, sometimes sold under the label of " Bonephones ", are headphones that work via the transmission of vibrations against the side of head, transmitting the sound via bone conduction.
