Iron, Cobalt and Nickel.
Well electromagnets have great power so it is understandable that someone would use it to pick up heavy metals.
Electromagnets pick up metals because when a current flows through the wire coils, it creates a magnetic field. This magnetic field attracts metallic objects, such as iron or steel, towards the electromagnet. The magnetic force overcomes the force of gravity, allowing the electromagnet to pick up metal objects.
Electromagnets are used in metal scrap yards because they can easily pick up and sort large quantities of ferrous metals from non-ferrous metals. By using an electric current to create a magnetic field, electromagnets attract and collect ferrous metals such as iron and steel, allowing for efficient separation and processing of different types of metals.
A magnet is built in the crane to pick up cars and other vehicles.
Electromagnets are used in scrapyards to pick up and drop metals that are magnetic because electromagnets are temporary which means you can turn it on and off. They are also used in hospitals and opticians to get metal out of your eye or body, You don't use a normal magnet because if you were in the middle of taking something out of someones eye you would need to be able to stop immediately in case you end up causing more damage.
The use for the electromagnet is to pick up scraps in junk yards. Electromagnets can be 'turned off' so you can pick something up and drop it in another place. You can't do that with a permanent magnet. They have other uses like locks, relays switches. Look up electromagnets in wikipedia.
Yes. There are huge electromagnets suspended from cranes that could do that.
Ferrous metals like steel. Electromagnets function the same as any other magnet but are only activated by the introduction of electrical current through an insulated wire that is normally coiled around a core of ferromagnetic material, such as soft iron.
pick things upAnother AnswerElectromagnets are necessary for an electric motor to work. Electromagnets are used in ink jet printers to release ink, they activate relays and solenoids. Electromagnets are inside automotive fuel injectors. The old CRT televisions wouldn't work without some high powered electromagnets. Computers would be useless without electromagnets that operate disk drives and relays. Electromagnets are an essential part of all transformers.Essentially, modern technology would come to an end without electromagnets.
Electromagnets have several uses. They are used in cranes to pick heavy metal objects, to lift tiny metal scraps from wound by doctors, motor and generators, electric bells, loudspeakers, etc.
Both magnets and electromagnets have a magnetic field that can attract or repel objects. They can both be used to pick up and manipulate metal objects. Both magnets and electromagnets rely on the alignment of the magnetic domains in their material to generate a magnetic force.
Scrap yards commonly use electromagnets mounted on cranes or forklifts to lift and move large metal objects such as cars, appliances, and steel beams. These electromagnets are typically powered by electricity and can be turned on and off to easily pick up and release metal pieces.
