← ScienceWhich risk increases significantly when a nickel-iron transformer core exceeds its Curie temperature?
A)Core material phase separation
B)Spontaneous domain wall motion
C)Increased hysteresis power loss✓
D)Enhanced eddy current generation
💡 Explanation
Increased hysteresis power loss results because surpassing the Curie point forces a phase transition during which the ferromagnetic alignement is lost. Because above that temp thermal agitation disrupts domains, therefore hysteresis loss increases, rather than other material breakdown modes.
