A magnet attracts other metal objects to it. This is done by combining the following materials: iron, boron, and neodymium. These materials make a magnet, and a magnet can also be made by rapping a copper wire around iron and running electricity through it, making an electromagnet.
An electromagnet is a controllable magnet. It can be switched on and off.
This is useful for all kinds of applications. The magnet can attract an armature, causing physical movement. This can be used to make a heavy duty switch (as in relays and contactors ), or used to unlatch doors and locks etc.
The biggest and most obvious use in industry, is to lift piles of scrap iron using a crane. The magnet is energized when lifting and switched off when you want the scrap to drop.
Magnets attract sure materials eg.
iron
steel
nickel
cobalt
Magnetic materials are interested in the poles of the magnet.
On a magnet the poles are at either finish of the magnet. Poles occur in pairs of equal strength.
One pole - North seeking pole - N pole- inform roughly to the Earth's North Pole.
Other pole - South - S pole
Like poles repel
Unlike poles attract
Force between magnetic poles decreases as their separation increases.
The uses of a magnet is holding things together, lifting and separating iron and steel objects from other non-magnetic materials, used in compasses to find directions, used in some electrical appliances.
Magnets moved past coils of wire generate all the electricity on Earth.
Magnets will attract or push away a coil of wire with a current flowing in it. All electric motors use this principle. Magnets make loudspeakers and headphones work.Electromagnets keep doors closed in keypad operated locks
you can do many things such as making a compass,a tv,acomputer and much more.
Magnets can be used for anything that arracts a magnet. for example steel or iron. And for roallar coasters and looking inside your body
it attracks magnetic particles .
Magnets for suspension springs for clocks
Several different metals can be used in magnets. Iron is perhaps the most common metal used in permanent magnets, but alloys such as Alnico (Aluminum, Nickel, and Cobalt) can also make very strong permanent magnets.

actually nickel, cobalt, and several rare earths are used as magnets too, but iron is the cheapest.
No, magnetite is used in magnets. Gold is used in jewelery.
Magnets are used in compasses.
how can magnets be used to help with recycling
how can magnets be used to help with recycling
Lead is used in magnets.
Nickel is used more in magnets
they use magnets to concentrate energyto them
Magnets of different strength are used.

The motors for windows have magnets in them.
it is used for magnets. :)
Magnets are (literally) the core of guitar pickups.
