Where use electromagnets?
Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
What kinds of electromagnets are in scrap yards?
well really all what it does is pick up metal bits off of cars or other things that are magnetics and than you cane move it to were you want to :)
An electromagnet has 20 coils around a wood stick and can pick up 5 paper clips Describe how you could modify the electromagnets to pick up more paper clips?
1. You could change the wood stick to an iron rod. 2. You can increase the number of coils. 3. You could increase the power (wattage) through the coil. 3 ways you can modify the electro-magnet to pick up more paper clips, probably more available.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
Why are electromagnets good?
Electromagnets are good because they are easily turned off which allows them to be used in a variety of practical applications. They are often used for picking up large loads of metal.
Why are electromagnets used for picking up heavy metals?
Well electromagnets have great power so it is understandable that someone would use it to pick up heavy metals.
What metals can electromagnets pick up for example stell etc.?
Iron, Cobalt and Nickel.
How electromagnets pick up cars?
A magnet is built in the crane to pick up cars and other vehicles.
Where use electromagnets?
Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
What was the purpose for inventing electromagnets?
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.
What are the some uses of electromagnets?
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.
What are the electromagnets called that are used at junkyards?
The electromagnets that are used in junkyards are called just that, electromagnets. They are used to sort out different types of metals.
Can an electromagnet pick up a train segment?
Yes. There are huge electromagnets suspended from cranes that could do that.
Electromagnets are different then homemade electromagnets. How?
Industrial Electromagnets Use higher quality metals for the coil winding. Also the windings are of different design and there are more of them. The metals used for the conductor are also of better quality material and have greater voltage sent to them.
How do scrap yards separate metals from non magnetic metals?
They use electromagnets to separate magnetic metals from non-magnetic metals/materials in scrapyards.
What can a electromagnet pick up?
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.
Do scrapyards use electromagnets?
Yes, they are an efficient way of sorting and transferring metals.
