Magnetostriction is a property of magnetic materials that causes them to change their shape or dimensions during the process of magnetization.The variation of materials' magnetization due to the applied magnetic field changes the magnetostrictive strain until reaching its saturation value, λ.
The magnetostriction characterizes the shape change of a ferromagnetic material during magnetization, whereas the inverse magnetostrictive effect characterizes the change of sample magnetization (for given magnetizing field strength ) when mechanical stresses are applied to the sample.
Magnetostriction is thermodynamically opposite to inverse magnetostriction effect. The same situation occurs for Wiedemann and Matteuci effects. For magnetic, mechanical and electric phenomena in fluids see Magnetohydrodynamics and Electrohydrodynamics .
The other energy cost to creating domains with magnetization at an angle to the "easy" direction is caused by the phenomenon called magnetostriction. [3] When the magnetization of a piece of magnetic material is changed to a different direction, it causes a slight change in its shape.
Magnetostriction, a property of ferromagnetic materials that causes them to change their shape when subjected to a magnetic field. The Joule effect (during Joule expansion ), the temperature change of a gas (usually cooling) when it is allowed to expand freely.
Magnetoresistance is the tendency of a material (often ferromagnetic) to change the value of its electrical resistance in an externally-applied magnetic field.There are a variety of effects that can be called magnetoresistance.
Common dissipative processes in magnetic materials include magnetostriction and domain wall motion. The coercivity is a measure of the degree of magnetic hysteresis and therefore characterizes the lossiness of soft magnetic materials for their common applications.
