What can magnets be used for?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

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

Answer 6

Magnets can be used for a variety of purposes, such as securing items in place (like on a refrigerator), generating electricity in power plants, and in technological devices like speakers and electric motors. They are also used in industries like healthcare for MRI machines and in transportation for magnetic levitation trains.

Answer 7

you can do many things such as making a compass,a tv,acomputer and much more.

Answer 8

Magnets can be used for anything that arracts a magnet. for example steel or iron. And for roallar coasters and looking inside your body

Answer 9

it attracks magnetic particles .
