The core of a transformer is made of soft iron because:
Correct answer: C. Iron is a good magnetic substance
- A. Iron is cheaper than copper
- B. Iron is a good conductor of current
- C. Iron is a good magnetic substance
- D. Iron has high melting point
Explanation
In order enhance the magnetic flux, the primary and secondary coils of transformer are wound on soft iron core and also hysteresis loop area of iron is very small that causes the decreases in hysteresis loss.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
