The core of a transformer is made up of:

Correct answer: C. Iron

  • A. Copper
  • B. Aluminium
  • C. Iron
  • D. Steel

Explanation

In transformers, soft iron cores are used because they reduce energy loss and they possess high magnetic permeability which allows coupling of magnetic flux between primary and secondary coils, hence the answer is C.

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.
