What causes a compass needle to get deflected when brought near a bar magnet?
What causes a compass needle to get deflected when brought near a bar magnet?
The magnetic field of the bar magnet causes the compass needle to align itself along the field lines, with the north pole of the compass pointing towards the south pole of the magnet and vice versa.
What is the significance of the orientation of a compass needle near a bar magnet?
What is the significance of the orientation of a compass needle near a bar magnet?
The orientation of the compass needle near a bar magnet demonstrates the presence and direction of the magnetic field lines, with the north-seeking pole of the compass pointing towards the south pole of the magnet and vice versa.

Study Notes
Magnetic Fields and Compasses
- A compass needle is deflected when brought near a bar magnet due to the interaction between the magnetic field of the magnet and the magnetic field of the Earth.
Compass Orientation
- The orientation of a compass needle near a bar magnet is significant because it indicates the direction of the magnetic field lines.
Iron Filings and Magnetic Fields
- Iron filings near a bar magnet demonstrate the magnetic field lines around the magnet.
- The iron filings arrange themselves in a pattern near a bar magnet because they are attracted to the magnetic field lines and align with them.
Magnetic Field Region
- The region surrounding a magnet where its force can be detected is called the magnetic field.
