Class 6 Science - HARYANA
Exploring Magnets
The chapter 'Exploring Magnets' in Class 6 Science introduces students to the fascinating world of magnetism, aligned with the Haryana Board (BSEH) curriculum. Students learn about how magnets were discovered, the difference between magnetic and non-magnetic materials, and the two poles of a magnet (North and South). The chapter covers practical applications like how a compass works and important rules such as 'like poles repel and opposite poles attract'. Understanding these fundamental concepts is crucial for board exams as it forms the basis for future physics topics related to electricity and electromagnetism.

Magnetic Materials
Materials like iron, nickel, and cobalt that get strongly attracted to a magnet.
Non-magnetic Materials
Materials like wood, plastic, and paper that do not get attracted to a magnet at all.
Poles of a Magnet
The two ends of a magnet, namely the North Pole and the South Pole, where the magnetic force is strongest.
Magnetic Attraction and Repulsion
Like poles (North-North or South-South) push away from each other, while opposite poles (North-South) pull towards each other.
Finding Directions
A freely suspended bar magnet always aligns in the North-South direction, which is the principle used in a magnetic compass.

Board Exam Info
In the Haryana (BSEH) Class 6 Science examinations, this chapter typically carries around 4 to 6 marks. Common question types include fill in the blanks, true or false, differentiating between magnetic and non-magnetic materials, and drawing or explaining the direction-finding property of a bar magnet.
Frequently Asked Questions
What happens if a bar magnet is cut into two pieces?
Each piece becomes a complete magnet with its own North and South poles, no matter how many times you cut it.
Why do magnets lose their properties?
Magnets can lose their magnetic properties if they are heated, dropped heavily from a height, or hammered.
Is plastic a magnetic material?
No, plastic is a non-magnetic material because magnets do not attract it.
