Which one of the following materials is more suitable for making cores of transformers?
Correct answer: A. Soft iron
- A. Soft iron
- B. Copper
- C. Nickel
- D. Aluminium
Explanation
The core of a transformer is made of soft iron because it has high permeability so ,it provides complete linkage of magnetic flux of the primary coil to the secondary coil.

About Transformers
Transformers transfer alternating electrical energy between coils by mutual induction, with voltage ratio determined by the turns ratio. The topic covers step-up and step-down transformers, current changes, ideal power conservation and practical losses such as heating and flux leakage. A transformer requires changing magnetic flux, so it does not operate with steady direct current.
