Which outcome occurs when strain is applied to magnetostrictive material?

A)Change in magnetic domain orientation
B)Increase in electrical resistivity
C)Decrease in thermal conductivity
D)Shift in optical absorption spectrum

💡 Explanation

Applying strain impacts magnetostrictive materials via magnetoelastic anisotropy; because mechanical stress alters domain alignment. This rotation influences ferromagnetism giving magnetization, therefore domain direction rotates in alignment with stress, rather than options like resistivity changes.
