← ScienceWhich potential outcome arises in an overloaded ferrite-core inductor?
A)Curie temperature threshold is exceeded✓
B)Eddy current losses are minimized
C)Magnetostriction effects become negligible
D)Coercivity of the material decreases
💡 Explanation
Exceeding current load causes excessive heat due to core losses; thermal energy drives the ferrite core towards its Curie temperature via the Curie-Weiss law. Above this point, ferromagnetism disappears because thermal agitation overcomes the magnetic ordering, therefore permeability drops sharply, rather than maintaining performance or lessening effects.
