Attractive facts of magnet | Facts about magnets | Facts About Magnets for Kids
- A magnet is a very special metal. When a magnet goes near a special kind of metal or other magnets, and the poles (sides) touching are opposite, it will pull, or attract the other metal or magnet closer.. The field of the "soft" magnet increases with the current.
- A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.

2)Magnets are ancient. Well, today’s man-made magnets may not be so ancient, but the Chinese are said to have used lodestone, a natural magnet as far back as date. In fact, ancient mariners are said to have used lodestones to help them navigate.A lodestone is a naturally magnetized piece of the mineral magnetite. They are naturally occurring magnets, which can attract iron. The property of magnetism was first discovered in antiquity through lodestones.
All magnets are made of a group of metals called the ferromagnetic metals. These are metals such as nickel and iron.
Neodymium iron boron (NdFeB)
Samarium cobalt (SmCo)
Alnico
Ceramic or ferrite magnets
-Magnets attract ferromagnetic materials, such as iron, nickel, and cobalt.
-All magnets have two poles: north pole and south pole. There are no magnets containing only one pole.
- Like poles of two magnets repel each other; opposite poles of two magnets attract each other.
-The magnetic force of a magnet is stronger at its poles than in the middle.
6)Did you know that you can easily turn common items like paperclips and iron nails into a temporary magnets? A temporary magnet acts like a permanent magnet when it is within a strong magnetic field. However, a temporary magnet looses it’s magnetism when the magnetic field disappears.
7)Powerful electromagnets are used in high-speed trains, called Maglev trains. These these trains will float over it’s track, reducing friction and allowing the train to run very efficiently.Many roller coasters use electromagnets to push the cars along the tracks.
8)Magnetic resonance imaging machines use magnets, and they generate stronger fields than the Earth. In fact, it is about 60,000 times stronger than the Earth’s.
9)The biggest magnet in the world is the one you are standing on right now! At the earth's center, its outer core is composed of moving liquid iron that makes the earth a giant magnet.
10)Another type of magnet is created when electricity passes through a wire. These magnets are called electromagnets. About 200 years ago, scientists discovered that electricity and magnetism are close cousins. An electrical current produces a magnetic field, and a moving magnet makes an electric current.

What are magnets attracted to for kids?
The main metals that are attracted by magnets are iron, cobalt and nickel. You can turn one of these metals into a magnet by rubbing it with a magnet!
What are 5 things that your magnet is attracted to?
Metals that attract to magnet Metals that naturally attract to magnets are known as ferromagnetic metals; these magnets will firmly stick to these metals. For example, iron, cobalt, steel, nickel, manganese, gadolinium, and lodestone are all ferromagnetic metals.
How do magnets attract?
Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field. The piece of iron has become a magnet.
What is a magnet facts for kids?
Magnets have invisible magnetic fields which attract and stick onto steel items. If you attach a bar magnet to a piece of wood and float it in a bowl of water, it will slowly turn and the magnet's North Pole will point towards the Earth's North Pole.
What is magnet in science for kids?
Magnetism is what gives magnets their ability to attract objects made of iron or steel. A magnet creates around itself a region of space with special properties. This region is known as a magnetic field. When two magnets come near each other, their fields create forces that attract or repel.
