← ScienceWhich consequence results when crystalline anisotropy fails in a ferromagnet?
A)Demagnetization occurs from domain alignment
B)Increased saturation magnetization is observed
C)Coercivity reduces below acceptable limits✓
D)Increased magnetostriction dampens oscillations
💡 Explanation
When crystalline anisotropy fails, domain alignment randomizes because the preferred magnetization directions are not maintained; therefore decreased coercivity results, as a smaller field causes full demagnetization, rather than maintaining alignment.
