Class 6 Science Curiosity Chapter 4 Exploring Magnets
If you are looking for Class 6 Science Curiosity Chapter 4 Exploring Magnets solutions then you are at the right place.
Q: What are magnetic and non-magnetic materials?
A: Magnetic materials are attracted towards a magnet (e.g., iron, nickel, cobalt), while non-magnetic materials are not attracted towards a magnet (e.g., wood, plastic, glass).
Q: What are the poles of a magnet?
A: A magnet has two poles: the North pole and the South pole. The ends of the magnet where most iron filings stick are called poles.
Q: Can a magnet have only one pole?
A: No, a magnet always has two poles. Even if a magnet is broken into smaller pieces, each piece will have both North and South poles.
Q: How does a freely suspended magnet behave?
A: A freely suspended magnet always comes to rest along the north-south direction, with its North pole pointing towards the Earth’s magnetic north.
Q: What is a magnetic compass and how does it work?
A: A magnetic compass is a device used for finding directions. It contains a magnetized needle that can rotate freely and always points in the north-south direction.
Q: How do magnets interact with each other?
A: Unlike poles of magnets (North-South) attract each other, while like poles (North-North or South-South) repel each other.
Q: Can magnetic force act through non-magnetic materials?
A: Yes, magnetic force can act through non-magnetic materials like wood, cardboard, plastic, and glass.
Q: How can you identify a magnet without using any other material?
A: A magnet can be identified by its property of repulsion. When brought close to another magnet, like poles will repel each other.
Q: What precautions should be taken while handling magnets?
A: Magnets should not be heated, dropped, or hammered. They should be kept away from electronic devices and stored properly with unlike poles on the same side, separated by a piece of wood.
Q: How does the Earth behave in relation to magnets?
