The north pole of the magnet is brought near a metallic ring as shown in figure. The direction of induced current in the ring (if looked from upside) will be
Options
- Aanti-clockwise.
- Bclockwise.
- Cfirst anti-clockwise and then clockwise.
- Dfirst clockwise and then anti-clockwise.
Correct answer
A. anti-clockwise.
Step-by-step solution
As the north pole of the magnet is brought near the metallic ring, the downward magnetic flux linked with the ring increases.
According to Lenz's law, the induced current in the ring will flow in a direction such that it opposes the change in magnetic flux. To oppose the increasing downward flux, the induced current must produce an upward magnetic field.
Using the right-hand grip rule, an upward magnetic field is generated when the current flows in an anti-clockwise direction. Therefore, when viewed from above, the direction of the induced current in the ring will be anti-clockwise.
Answer: anti-clockwise.
