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 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 :)
What is an advantage of using an electromagnet over a permanent magnet?
The advantage of an elecromagnet is that you can turn it on and off with a simple switch. So for example if you want to pick up a scrap car with a crane/electromagnet and move it, you can turn the electromagnet off when you want to release the car. You could not do the with a permanent magnet obviously.
What do magnets do in a scrap yard?
They are attached to cranes and are used to lift up heaps of scrap metal
List three uses for electromagnets?
1. Scrap yards sometimes use it to lift heavy pieces of MAGNETIC materials e.g steel. 2. In speakers they use electro-magnets so the speaker can actually play the sound. It is used in the speakers diaphragm. 3. In hospitals to remove magnetic particles from a patients eye after a accident. hope this helps!!Lucy:)
Why is an electromagnet better that a bar magnet?
Electromagnets can have higher "domain currents" than permanent magnets, and have no non-aligned nor anti-aligned domains like permanent magnets tend to have (or get over time).
How does a scrap yard crane work?
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
What is a lifting magnet?
A lifting magnet is an electromagnet that is meant to hold or move material that comes in contact with the magnet. This is the opposite of a traction magnet.

How do scrap yards separate metals from non magnetic metals?
They use electromagnets to separate magnetic metals from non-magnetic metals/materials in scrapyards.
Why can't we use a permanent magnet in a scrap yard?
You need to use an electromagnet in a scrap yard so that you can let go of the pieces of scrap that you pick up. A permanent magnet would not allow you to let go.
How would the use of electromagnets help the scrap metal industry?
It does in that they use very large magnets for the lifting and dropping of scrap into compacting machines and processing machines. It could - though currently does not - have application as a means of transportation, should maglev trains ever come into being.

What happens inside a scrap heap magnet?
Scrap heap magnets are basically electromagnets. Electromagnets are simply wire coils usually would around an iron core. When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet. The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet.
How do you get Gigawat on dragonfable?
Go to crazy doctor bloke (can't remember name) and fight his creations and keep the scrap metal keep collecting then trade for gigawat or buy special item (plutonium core i think?) or something and he can give you a better version
Why are electromagnets used in the process of corn oil production?
Electromagnets aren't "directly" used in corn oil production. Electromagnets find a lot of industrial applications, but usually only to lift things or hold them in place. This means that they won't be lifting or holding stuff that isn't ferromagnetic. There may be electromagnets in use within, say, and ADM or Cargill corn oil plant, but it isn't like they are critical. Now if we were lifting scrap iron from a pile in a wrecking yard into a gondola car, the electromagnet is the way to go.
