← ScienceWhich risk increases when increasing temperature of ferrite core inductor?
A)Curie point demagnetization occurs✓
B)Eddy current losses decrease
C)Hysteresis loop area increases
D)Core permeability reaches infinity
💡 Explanation
Curie point demagnetization occurs because thermal energy disrupts the alignment of magnetic domains leading to loss of ferromagnetism. Increased thermal agitation overcomes the exchange interaction, therefore, domain alignment is lost rather than increased efficiency if eddy losses decrease.
