In a transformer heat is produced due to eddy current in :
Correct answer: B. Iron core
- A. Primary coil
- B. Iron core
- C. Secondary coil
- D. All of these
Explanation
The magnetic flux changes through solid conductor (core material), induce current (i.e eddy current) are setup in closed path in the body of conductor. It results in power dissipation and heating of core material.

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.
