← ScienceWhich magnetic outcome occurs when a crystal undergoes deformation?
A)Magnetostriction induces dimensional changes.✓
B)Curie temperature spontaneously elevates.
C)Magnetic saturation dramatically decreases.
D)Exchange coupling increases sharply.
💡 Explanation
Magnetostriction induces dimensional changes in a ferromagnetic crystal when strain alters magnetic domain alignment because atomic spacing variation affects magnetic anisotropy; therefore the crystal shape deforms due to altered magnetization, rather than temperature shifts or saturation changes.
