In a transformer, the core is made of soft iron to reduce

  1. Hysteresis losses
  2. Eddy current losses
  3. Force opposing electric current
  4. None of the above

Correct answer: Hysteresis losses

Solution

Soft iron has a small hysteresis loss because it can be magnetized and demagnetized easily. In transformers, this reduces energy loss during repeated magnetization. Therefore the core is made of soft iron to reduce hysteresis losses.
