What is Magnetostriction?Magnetostriction DefinedMagnetostriction is the property of certain magnetic materials to change their shape or dimensions in response to an external magnetic field.Discovery and ResearchThe phenomenon was first noted by James Joule in 1842, establishing a foundational understanding of how magnetic fields affect materials.Key Influencing Factors The magnitude and direction of the applied magnetic field The saturation magnetizationof the material The magnetic anisotropy o
