Those magnetic materials are best suited for making armature and transformer cores which have ________ permeability and ________ hystersis loss
Correct answer: C. high, low
- A. high, high
- B. low, high
- C. high, low
- D. low, low
Explanation
Armature and transformer cores need high permeability so flux is established with a small magnetising force, and low hysteresis loss to reduce heating during repeated magnetisation. These requirements correspond to c.
