PHYSICS [2 Mark Question Answer]

The substances that can be easily magnetized and are attracted towards magnet are known as magnetic materials. Cobalt, nickel, iron are some examples of magnetic materials. Coins contain nickel, that is why they are attracted towards magnets.

Magnetic substances are those which are attracted by a magnet. Examples of magnetic substances are iron, nickel, cobalt, etc. Non-magnetic substances are those which are not attracted by magnets. Examples of non-magnetic substances are wood, copper, plastic, eto

Ferrite, a ceramic-like material with magnetic properties that are useful in many types of electronic devices. Ferrite is used in: Permanent magnets. Ferrite cores for transformers and toroidal inductors. Computer memory elements.

Four devices that uses artificial magnet:
1. Loudspeaker
2. Telephones
3. Radios
4. Television

Natural magnets are weaker than artificial magnets and are often irregular in shape. Whereas artificial magnets can be made of any strength and can be magnetized and demagnetized easily as per the requirements. That's why artificial magnets are preferred over natural magnets.

Magnets which are made from iron in different shape and sizes for different uses are called artificial magnets. It is a magnetized piece of iron, stee cobalt, or nickel. These magnets are of different sizes and shapes.
