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 do magnets do in a scrap yard?
They are attached to cranes and are used to lift up heaps of scrap metal
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.
Where are temporary magnets used?
It makes sense that since some magnets are called "permanent magnets," other magnets should be called "temporary magnets." But since when did English make sense? We usually call them "electromagnets" instead. Electromagnets are used in most electric motors, and cranes that lift scrap metal. They're also used in relays and the write heads of tape recorders (including video tape recorders).
What is the best metal to make an electromagnet out of?
An iron core and copper wire (that is coated with an insulator) are used all the time to make electromagnets.
How are magnets used in junk yards?
Rather than "permanent" magnets, the large electromagnets used in junkyards only create a magnetic field when electric current flows through them. They are used to lift iron and steel scrap, and to separate it from non-magnetic scrap. The cranes have an electric generator connected to a wire coil in the large round lifting disc. When the power is on, its magnetic field attracts heavy iron and steel to it. When the scrap is positioned where they want it, they cut the power to the electromagnet and the scrap drops. They are attached to cranes and are used to lift up heaps of scrap metal
Where are electromagnets used in industry?
An electromagnet is used in an electrical engine, but an electrical engine contains normal magnets too.

Where are elecromagnets used?
Some are used in scrap yards to remove large pieces of metal, like cars. You can look up how they work in wikipedia. ;)
Where are electromagnets used?
fire bells tv's junk yards and a lot more
Can you show examples of electromagnetic change?
Electromagnets are used in places like scrap yards! to separate metals
How do electromagnets work-3 uses?
An electromagnet is essentially a metal core encased in an electric wire. Without electricity, the 'magnet' doesn't work. Run a current through the wire, and the magnet becomes active. One of the commonest uses - is in a scrap metal yard - where it's used to lift large quantities of scrap onto a conveyor belt for sorting.
Can lids are used for what?
they are melted and sold as scrap metal

What are the uses in the 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.
Were scrap metal used to build Spitfires in 1940?
Yes
