Ferromagnetic material used in Transformers must have _________.
Fill in the blank with the correct answer from the options given below.
Answer & explanation
Correct answer: option 2
A ferromagnetic material core used in the transformer must have high permeability so that it may show a high value of magnetic induction for the given magnetizing field. It should have low hysteresis loss in order to decrease energy losses.
The correct answer is Option (2) → High permeability and Low Hysteresis loss
