Magnetic Properties of Matter: Practice Problem & Solution

24. If a diamagnetic substance is brought near the north or the south pole of a bar magnet, it is: (2009)
Repelled by the north pole and attracted by the south pole
Attracted by the north pole and repelled by the south pole
Attracted by both the poles
Repelled by both the poles

Solution Explained:

To solve this problem, we apply the core principles of Magnetic Properties of Matter. Understanding the underlying formula is key to arriving at the correct answer below:

Diamagnetic materials tend to move from regions of stronger magnetic fields to weaker magnetic fields. Since the magnetic field is strongest near both poles, the substance is repelled by both the north and south poles.
