Which transformer loss arises from repeatedly reversing the magnetisation of the core?
AHydraulics
BHyphenation
CHydrolysis
DHysteresis
Answer & Solution
Correct answer: D. Hysteresis
1. The core is magnetised one way, then the other, every cycle.
2. Driving that reversal costs energy each time.
3. The magnetisation of the core is repeatedly reversed by the alternating magnetic field.
4. That loss is called hysteresis.
