Answer 1

Answer:

Properties of Magnets are as follows :

• A magnet is an object which attract materials like Iron, cobalt, Nickel, steel.

• A magnet has two poles near its ends : North pole and South pole.

• The End of a freely suspended magnet which will point towards the North direction is called North pole of magnet. and other end pointing towards south is called South pole of magnet.

• Like poles of a magnet repel each other.

• Unlike poles of a magnet attract each other.

Some uses of Magnets :

• Magnets are used in Television, Radios, speakers, Refrigerator doors, Cassettes, tapes, hard disks etc.
• Magnets are also used in making Electric generators and electric motors.
• Magnets are also used in Magnetic Resonance imaging (MRI) technique that is used to scan inner human body parts.

Answer 2

$\mathtt{\huge{\underline{\purple{Magnet:-}}}}$

A magnet is a material that has both attractive & directive property. It attracts small metallic particles. The property of metal to be attracted or attraction is called magnetism.

It is of two types :-

• Natural :- It is a load stone, magnetite or black iron oxide (Fe3O2) which have property of attracting iron.

• Man-Made :- The pieces of iron can be attracted by a magnet based on property of natural magnet , having regular shape & size as compared to natural magnet.

✭ State the important property of magnets.

$\mathtt{\huge{\underline{\green{Answer:-}}}}$

➝ The important property of magnets are :-

⚜ Attractive Property :-

• A magnet attracts small pleces of metal . When a magnet is brought near a heap of iron filings, the ends of the magnet show the greatest attraction.

• At the ends, magnetic attraction is the maximum, are called poles of the magnet. Thus every magnet has two poles.

⚜ Directive property :-

• When a magnet is suspended or pivoted freely, it aligns itself in the geographical north-south direction.

• The pole of the magnet which points towards north is the north-seeking or north pole. The pole which points towards the south is called the south-seking or south pole of the magnet.

⚜ Like poles repel and unlike poles attract :-

• If the north pole of a magnet is brought near the noth pole of a magnet they repel each other. Two south poles also repel each other. So, north and south poles always attract each other.

• The law of magnetic poles which states that like magnetic poles repel, and unlike magnetic poles attract each other.

⚜ Magnetic induction :-

• A magnet induces magnetism in a magnetic substance placed near it . So, it is called magnetic induction.

• When N-pole of a powerful magnet is placed close to a soft iron bar the closer end of the bar becomes S-pole and the farther end N-pole. As a result, the magnet attracts the iron bar. Thus induction precedes attraction.

⚜ Magnetic poles always exist in pairs :-

• During isolation of the two poles of a magnet from each other by breaking the magnet in the middle, each broken part is found to be a magnet with N- and S-poles at its ends.

• During breaking these parts further, each part again is found to be a magnet. So unlike electric charges, magnetic monopoles do not exist. Every magnet exists as a dipole.
