Each magnet has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces. Hence, the total number of poles will be four.

The materials which are attracted towards a magnet are known as magnetic materials. For example- iron, cobalt etc.

The materials which are not attracted towards a magnet are known as non-magnetic materials. For example- plastic, glass etc.

Each use: 1 Mark
1) A magnetic compass can be used to find directions.

2) A magnet can be used to separate magnetic material from a non-magnetic material.

Answer: 2 Marks
Iron nails, nickel, steel pen, and cobalt will be attracted to magnet and rest of the materials are non-magnetic in nature, so they will not be attracted to a magnet.

Artificial magnets: 2 Marks
Examples: 1 Mark
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.

Entire Conversion: 5 Marks
The iron strip can be converted into a magnet by 'touch and stroke' method. For this, a bar magnet is required. The bar magnet is moved along the length of the iron strip. Thus, the bar magnet is lifted from the other end and brought to the starting point again with the same pole of the bar magnet its moved back. On repeating the process for at least 40 to 50 times, the iron strip will become a bar magnet with two poles. 

Destroying magnetic properties: 2 Marks
Safety: 3 Marks
Magnets lose their properties if they are heated, hammered or dropped from some height. Also, magnets become weak if they are not stored properly.
Ways to keep magnets safe:
1. They should be kept in pairs with their unlike poles on the same side.
2. For horseshoe magnet, one should keep a piece of iron across the poles.
3. Take care to protect the magnet against mechanical shock. Some magnets are brittle. They will crack or break if they fall on a hard surface or bang against metal or another magnet. Do not strike them with a hammer.

Each Point:  1 Mark
1. A magnet attracts magnetic materials towards itself.
2. A freely suspended bar magnet always aligns in the north-south direction.
3. Unlike poles attract each other and like poles repel each other.

A compass is an instrument which is used to find the direction of a magnetic field. A compass consists of a small metal needle which is magnetized and is free to turn in any direction. Therefore, in the presence of a magnetic field, the needle is able to line up in the same direction as the field.
Compasses are mainly used in navigation to find direction on the earth. This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south. Once you know where north is, you can figure out any other direction.
