Question

Poles, attracts, east-west, north-south, like, opposite, repel, magnetic.
Fill in the blanks in the following passage (s) from the words given above.
A magnet ___1__ small pieces of iron, nickel, cobalt, etc. The magnetic force of attraction is maximum in small regions near the ends of the magnet. These are called __2___ of the magnet.A freely suspended magnet always points in __3___ direction. The end pointing towards north is called north seeking pole or north pole. The other end which points towards the south is called south seeking pole or south pole. All the magnets attract __4___ poles of other magnets and also a few substances like iron, nickel and cobalt. Thus, if an unknown substance is attracted by a magnet, we cannot be sure whether it is a magnet. But like poles of magnet ___5__ each other. Hence, if there is repulsion between an unknown substance and the magnet, we can be sure that the unknown substance is a magnet. The substances which are attracted by magnets are called __6___ substances.

Answer 1

Hint:A type of magnet named alnico is the strongest of all magnets. The density of field lines is highest near the poles. North pole of a magnet is attracted by the south pole of another magnet. The south pole of the earth’s magnet takes the north pole of the magnet.

Complete answer:
-To begin with, we should know the properties of a magnet. There are various terms related to a magnet. Magnets are the substances which are made by passing huge amounts of current through the soft iron core. The magnets can be turned into permanent magnets if we use soft iron core. There are electromagnets as well, which are the types of magnets which show magnetism when there is flow of electric current through the iron core.
-One of the most important properties of a magnet is that it attracts magnetic materials such as iron, nickel, cobalt, etc. There are other substances which are not attracted by magnets although they are metals such as aluminium, copper, gold, etc. The strength of the poles is maximum, as the density of the field lines is maximum in those regions.When we suspend a magnet freely it always aligns along the north-south direction. This is because the north pole of the magnet attracts the south pole of the earth’s magnetic field and vice versa.
-If we bring a north pole of one magnet closer to the north pole, then they will repel. But we bring the north pole closer to the south pole, then they will attract.There are two types of substances, one is magnetic substances and the other is non-magnetic substances. Magnetic substances are attracted by magnets while the non-magnetic substances are not.
The answers are as follows:
1) Attracts
2) Poles
3) North-south
4) Opposite
5) Repel
6) Magnetic

Note:While answering this question remember that a magnet always aligns itself in the north-south direction. The magnetic north pole of the magnet aligns towards the south pole of the earth’s magnetic field and vice versa. It has nothing to do with the east-west direction of the earth’s magnetic field.
