NCERT Solutions for Curiosity Chapter 4 Exploring Magnets
Updated on 2026-09-05
About this chapter
A magnet is an object that attracts iron, nickel and cobalt. Magnets found in nature are called lodestones ; the bar, U-shaped and ring magnets in your laboratory are artificial magnets . Materials pulled towards a magnet are magnetic materials (iron, nickel, cobalt, steel). Materials that are not pulled are non-magnetic materials (wood, rubber, plastic, glass, paper, copper, aluminium). Every magnet has two poles — a North pole and a South pole — at its two ends, where the pull is strongest. Poles always come in pairs ; a single pole cannot exist, no matter how small you break the magnet. A freely suspended magnet always rests along the north-south direction , because the Earth itself behaves like a giant magnet. This is the idea behind the magnetic compass , and behind India's old matsya
