Eddy current is produced when:
Correct answer: A. A metal is kept in varying magnetic field
- A. A metal is kept in varying magnetic field
- B. A metal is kept in steady magnetic field
- C. A circular coil is placed in a steady magnetic field
- D. A current is passed through a circular coil
Explanation
Therefore, the correct option is A) A metal is kept in a varying magnetic field. This scenario leads to the creation of eddy currents in the metal due to the changes in the magnetic field inducing electrical currents within the 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.
