Fun with Magnets Class 6 notes - Chapter 13

What is Magnet?

Objects which attract magnetic materials like cobalt, iron, and nickel are called as a magnet.

A magnet was discovered by an ancient Greek shepherd named Magnes. Therefore, this naturally occurring mineral – magnet was named by the discover’s name. The magnets, obtained naturally from a Magnetite rock, are called as the natural magnets and those magnets prepared by the combination of certain mineral ores are called as the artificial magnets.

Magnetic Materials: Cobalt, iron, and nickel are some examples of Magnetic Materials. These materials easily attract towards a magnet.

Non-magnetic Materials: Aluminum, zinc, wood, and rubber are called the Non-magnetic Materials, as these materials are not attracted towards the magnet even when they are brought closer to the magnets.
