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.
