If we give a direct current to the transformer's primary coil, then there will be:
Correct answer: A. No emf produced in the secondary coil
- A. No emf produced in the secondary coil
- B. More emf in the secondary coil
- C. Equal emf produced in the secondary coil
- D. Less emf produced in the secondary coil
Explanation
A direct current will produce no varying magnetic field and therefore, no emf will be generated in the secondary coil.

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.
