Fun with magnets · चुंबकों के साथ मज़ा
A free Physics lesson for Class 6 children.
A magnet attracts things made of iron, nickel and cobalt. These are magnetic materials.
Every magnet has two poles, north and south. The poles are where the pull is strongest.
A freely hanging magnet always comes to rest pointing north and south. That is how a compass works.
Like poles repel each other and unlike poles attract each other.
A magnet loses its strength if it is heated, hammered or dropped. Store magnets in pairs with unlike poles together.
