FAQs on Poles of Magnet Video Lecture - Crash Course for Class 6

1. What are the poles of a magnet?
Ans. The poles of a magnet are the regions where the magnetic force is strongest. Every magnet has two poles: the north pole and the south pole. The north pole is the end that seeks the Earth's geographic North, while the south pole seeks the Earth's geographic South.
2. Why do magnets have north and south poles?
Ans. Magnets have north and south poles due to the alignment of their internal magnetic domains. These domains are tiny magnetic regions within the material that align in a specific direction when magnetized. The opposite poles attract each other, which is why a north pole attracts a south pole, while like poles repel each other.
3. Can a magnet exist without both poles?
Ans. No, a magnet cannot exist without both a north and a south pole. Even if a magnet is cut in half, each piece will still have both a north and a south pole. This phenomenon is known as magnetic dipole, meaning every magnet, regardless of size, has both poles.
4. How can you identify the north and south poles of a magnet?
Ans. You can identify the north and south poles of a magnet using a compass. The needle of a compass is a small magnet itself, and it will align itself with the Earth's magnetic field. The end of the compass needle that points towards the north indicates the location of the magnet's south pole, while the opposite end points towards the magnet's north pole.
5. What happens if you bring two magnets close together?
Ans. When two magnets are brought close together, they will either attract or repel each other depending on their poles. If the north pole of one magnet is brought near the south pole of another, they will attract each other. Conversely, if two north poles or two south poles are brought close, they will repel each other.
