Hi,

Your answer.

Question-》 Define magnet ?

Answer -》 Substance / material having the property of attracting magnetic materials is known as magnet.

☆ Magnets are of two types .

1. Natural magnet -》 Natural occuring minerals or ores having magnetic property is known as natural magnet.

2. Artificial magnet -》These magnets are the magnets which we can make ourself, we can give shape size in these magnets.

☆ examples of magnets.

1. U shaped magnet

2. Compass needle

3.Ball shaped magnet

☆ There are four properties of magnet.

1. Attractive nature -》If a magnet attracts any magnetic material or other magnet, so it's is the attractive nature of the magnet.

2. Directive property -》When a magnet is suspended freely, it always alings itself toward north-south direction, the pole pointing toward north direction after suspended freely is known as ( North Seeking Pole ) and the pole pointing towards south direction after suspended freely is known as ( South Seeking Pole ).

3. Pole exist in pair -》 If, you cut a magnet into many pieces so it is sure that magnet has always two poles ( North pole and south pole ).

4. Inductive nature -》When certain substances like Iron, cobalt, nickle placed near a bar magnet they accquire magnetisation, this is known as Induced magnetisation, this phenomenon is known as magnetic Induction and in this process when a awl pin get cling to the magnet so, it also behave as a magnet, this is known as Inductive nature.

:-) Hope it helps !

MAGNETS
Magnets are the substances or different materials which will attract iron-containing objects which points north and south once suspended. Magnets have a robust attraction of attracting magnetic /iron particles. Magnets are objects that have a north and South Poleat opposite ends. In magnets, opposite poles brought close to one anotherattract, and like poles repel.

TYPES OF MAGNETS

1. Natural Magnets
A natural magnet is a magnet that happens naturally in nature. All natural magnets area unit permanent magnets, that means they'll ne'er lose their magnetic power.Natural magnets isfound in sandy deposits in numerouselements of the globe. The strongest natural magnet material is lodestone, conjointly referred to as magnetic iron-ore. 

2. Artificial Magnets 
When magnets are created by individuals, they're called Artificial Magnets. There area unit 2 types ofartificial magnets: temporary and permanent. Temporary magnets area unit magnets that are not continuallymagnetic. Permanent magnets area unitthose magnets whose magnetic strength ne'er fades.

EXAMPLES OF MAGNETS

There area unit many sorts of magnets

1. Bar magnet
Bar magnet is cubical in form with poles at each ends.

2. Horseshoe magnet
Horseshoe magnet appears like a horseshoe and it's the strongest one.

3.U-shaped magnet 
U shaped magnet appears like a horseshoe magnet.

4.Compass needle 
A attractable pointer at intervals a compass, absolve to align itself with the Earth's magnetic flux.

PROPERTIES OF MAGNETS

1. Magnets attract objects of iron, metaland nickel. 
2. The force of attraction of a magnet is bigger at its poles than within themiddle. 
3. Like poles of 2 magnets repel one another. 
4. Opposite poles of 2 magnets attracts one another. 
5. If a magnet is suspended by a thread and if it's absolve to rotate, its South Pole can move towards the pole of the planet and the other way around.

HOW DO MAGNETS WORK? 

When a magnetism material (a material that's drawn to magnets) comes into contact with the magnet, the domains during this material align themselves with the domains within the magnet. Thus, the atoms in these materials, like steel, for instance, quickly tend to behave like small very little bar magnets.

All magnets have south and north poles. The South Pole of a magnet is of coursedrawn to the pole of another magnet. This attraction is what causes the piece of steel to stay to the magnet.

Non-ferromagnetic materials (materials that aren't drawn to magnets) don'tarrange into alignment with the magnetic domains and keep during a random formation.

Stainless steel, for instance, isn't a awfully smart magnetic material, therefore if you bit your magnet with one thing product of chrome steel it'll in all probability not persist with it.
