Bar Magnet Alignment
Bar Magnet Alignment
A freely suspended bar magnet will align itself with the Earth's magnetic field, with its north pole pointing towards the Earth's geographical north.
Magnetic Poles
Magnetic Poles
The ends of a magnet are called poles, and they are labeled North and South. The North pole of one magnet will attract the South pole of another magnet, and vice versa.

Like Poles Repel
When two magnets with the same poles (North-North or South-South) are brought close together, they will push away from each other.

Study Notes
Magnet Poles
- A freely suspended bar magnet aligns itself with the Earth's magnetic field, pointing roughly north and south.
- The pole that points north is called the north-seeking pole (or simply the north pole).
- The other pole is called the south pole.
- Poles are labeled with the capital letters N and S.
- A magnet always has two poles (dipole); single poles (monopoles) don't exist.
- The line connecting the two poles is called the magnetic axis.
Like and Unlike Poles
- Like poles repel each other.
- Unlike poles attract each other.
- This behavior is demonstrated by bringing the poles of two magnets close together, observing their interaction.
Exercise 3.2
- Identify the pair of magnets that will attract each other from the given diagrams.
- All magnets are equally strong.
- Correct answer is (c) N-S.
