Question

Which of the following will decrease the magnitude of eddy currents in a solid conductor?

• A. Strong varying magnetic field
• B. Larger area of cross-section of conductor
• C. Smaller area of cross-section of conductor
• D. None of these

Answer 1

The correct option is C Smaller area of cross-section of conductor

Smaller area of cross-section will increase the resistance of the object.

If resistance is increased, the magnitude of eddy current will decrease.

Hence, option $\left(C\right)$ is the correct answer.
