Understanding Compass Needle Deflection
When a compass needle shows deflection, it indicates that it is responding to a magnetic field. This deflection can occur in two scenarios:
1. Brought Near a Magnet
- When a compass needle is brought close to a magnet, it experiences the magnetic field produced by the magnet.
- The needle, which itself is a small magnet, aligns itself with the external magnetic field.
- The north pole of the compass needle will point towards the south pole of the magnet, causing a noticeable deflection.
2. Brought Near a Current-Carrying Wire
- A current-carrying wire generates a magnetic field around it due to the flow of electric current.
- When a compass needle is placed near this wire, it will also show deflection.
- The direction of the deflection depends on the direction of the current flowing through the wire, following the right-hand rule.
Conclusion
- Both situations cause the compass needle to deflect, confirming that option 'C' (both are true) is correct.
- This is an important principle in physics, illustrating the relationship between electricity and magnetism, as well as the fundamental characteristics of magnetic fields.
Understanding these concepts helps in grasping the basics of electromagnetism, which is crucial for further studies in physics.
