Question

Which of the following is an artificial magnet? (a) Bar magnet (b) Horse-shoe magnet (c) Disc shaped magnet (d) All of these​

Answer 1

Answer:

The correct options are

A Bar magnet

B Horse-shoe magnet

Magnets that are made from pieces of iron are known as artificial magnets. Artificial magnets are man-made magnets prepared by using elements like iron, cobalt, nickel or their mixture with other elements. Artificial magnets come in different shapes, for example, bar magnet, horseshoe magnet, cylindrical or ball-ended magnet.

Explanation:

Artificial magnets are the magnets in different shapes which are made from iron and its alloy. Artificial magnets are also known as hard magnets or permanent magnets. Bar magnet, horse shoe magnet, pot shaped and cylindrical magnets are examples of artificial magnets...

Answer 2

All of these are artificial magnets.

Important Points:

• Magnets are the materials that attract iron. Magnets are found naturally in the iron core.
• Magnetic materials are also made in laboratories. These are known as artificial magnets. Artificial magnets are made in different shapes. They are named according to their shapes. Artificial magnets are generally iron alloys.
• Artificial magnets are also known as hard magnets. These are made from iron by adding some additional elements such as nickel, cobalt, etc.
• Bar Magnet, Horse-shoe magnets, Disc-shaped magnet, and Cylindrical magnets are all artificial magnets.

• Every magnet has two poles, whether they are found naturally or they are made artificially.
