FAQs on Fun with Magnets - Introduction Video Lecture - Science Class 6

1. What are magnets used for?
Ans. Magnets are used for various purposes, such as sticking items to metal surfaces, generating electricity in generators, and in compasses for navigation.
2. How do magnets work?
Ans. Magnets work based on the alignment of their atoms. The atoms in a magnet are aligned in such a way that they create a magnetic field around the magnet, attracting or repelling other magnets or magnetic materials.
3. Can magnets lose their magnetism over time?
Ans. Yes, magnets can lose their magnetism over time. Factors like exposure to high temperatures, strong magnetic fields in the opposite direction, or physical damage can demagnetize magnets.
4. What are the two poles of a magnet called?
Ans. The two poles of a magnet are called the north pole and the south pole. The north pole of one magnet attracts the south pole of another magnet, while the same poles repel each other.
5. How can magnets be made stronger?
Ans. Magnets can be made stronger by increasing the number of magnetic domains aligned in the same direction. This can be achieved by using stronger magnetic materials, such as rare earth magnets, or by magnetizing the material in a specific way using an external magnetic field.
