Fun with Magnets

Magnet:- The substances having the properties of attracting iron are known as magnets.

Natural Magnets:- Certain rocks have the property of attracting pieces of iron. They also found that small pieces of these rocks have some special properties. They named these naturally occurring materials magnets.

Artificial magnets:- An artificial magnet is a magnet that is created by humans, usually by magnetizing materials like iron, steel, or other magnetic materials. For example, bar magnet, horse- shoe magnet, cylindrical or a ball-ended magnet.

Magnetic:- The materials which get attracted towards a magnet are magnetic – for example, iron, nickel or cobalt.

Non magnetic:- The materials which are not attracted towards a magnets are non-magnetic.

Poles:-

Each magnet has two magnetic poles—North and South.
A freely suspended magnet always aligns in the N-S direction.
Opposite poles of two magnets attract each other whereas similar poles repel one another.

Compass:- A compass is usually a small box with a glass cover on it. A magnetized needle is pivoted inside the box, which can rotate freely.

The compass also has a dial with directions marked on it. Its needle indicates the north-south direction when it comes to rest. The compass is then rotated until the north and south marked on the dial are at the two ends of the needle.

Cautions:-

👉Magnets lose their properties if they are heated, hammered or dropped from some height.

👉Magnets become weak if they are not stored properly
