When there is a change of flux in the core of a transformer due to change in current around it, eddy current is produced. What is the direction of this current?

1. Opposite to the current which produces it
2. Same as the current which produces it
3. Perpendicular to the current which produces it
4. None of the above

Correct answer: Opposite to the current which produces it

Solution

According to Lenz's law, the direction of the eddy current is such that it opposes the change in magnetic flux that produces it. This means the eddy current flows opposite to the current causing the flux change.
