When a magnet is brought near a magnetic compass, several notable effects occur due to the interaction between the magnetic fields. Here's a detailed explanation of the phenomenon.

Effect on Compass Needle
- The compass needle is a small magnet itself, usually made of iron or magnetized steel.
- It aligns itself with Earth's magnetic field, pointing toward magnetic north.
- When an external magnet is introduced, it generates its own magnetic field, which can disrupt the compass's natural alignment.

Deflection of the Needle
- The compass needle will respond to the stronger magnetic field from the external magnet.
- Depending on the orientation of the magnet, the compass needle may swing away from its original position.
- If the magnet is a bar magnet, one end will attract the compass needle, while the opposite end will repel it.

Factors Influencing the Interaction
- **Strength of the Magnet**: A stronger magnet will exert a more significant influence on the compass needle.
- **Distance**: The closer the magnet is to the compass, the more pronounced the effect will be.
- **Orientation**: The angle at which the magnet is brought near the compass also affects how the needle moves.

Temporary vs. Permanent Effects
- **Temporary Effect**: Once the external magnetic field is removed, the compass needle will return to pointing towards magnetic north.
- **Permanent Magnetization**: If the compass needle is exposed to a strong magnetic field for an extended period, it may become permanently magnetized, altering its original alignment.
In summary, bringing a magnet near a compass disrupts its alignment by exerting its magnetic force, leading to deflection based on various factors like strength, distance, and orientation.
