← ScienceWhich outcome occurs when thermal energy overcomes magnetocrystalline anisotropy in iron?
A)Paramagnetism replaces ferromagnetism✓
B)Magnetostriction induces cracking
C)Coercivity increases significantly
D)Hysteresis loops become square
💡 Explanation
Paramagnetism replaces ferromagnetism when sufficient increased thermal energy enables individual atomic magnetic moments to randomize, overcoming alignment imposed by magnetocrystalline anisotropy, because the magnetic order disappears when thermal energy dominates therefore switching to paramagnetism rather than maintaining magnetic order.
