← ScienceWhich outcome occurs when exceeding the Curie temperature in ferrite cores?
A)Magnetostriction reduces transformer output
B)Spontaneous magnetization disappears completely✓
C)Hysteresis losses sharply reduces
D)Eddy-current suppression drastically increases
💡 Explanation
Spontaneous magnetization disappears at the Curie temperature in ferrites because thermal energy overcomes magnetic ordering; therefore, the material becomes paramagnetic rather than experiencing magnetostriction, reduced hysteresis, or enhanced eddy-current suppression.
