Question:
A sphere of gold when brought towards a powerful magnet experiences
A sphere of gold when brought towards a powerful magnet experiences
Show Hint
Diamagnetic substances (like gold, bismuth, copper) are always weakly repelled by magnetic fields.
Updated On: Feb 18, 2026
- attractive force
- repulsive force
- zero force
- nuclear force
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Magnetic nature of gold.
Gold is a diamagnetic substance. Diamagnetic materials develop induced magnetic moments opposite to the applied magnetic field.
Step 2: Effect of magnetic field.
When a diamagnetic substance is placed in a non-uniform magnetic field, it is repelled from regions of stronger magnetic field.
Step 3: Conclusion.
Therefore, a gold sphere experiences a repulsive force when brought near a powerful magnet.
