What happens to the electromagnet when the circuit is closed?
An electromagnet if formed by pushing current through a coil. If the circuit is truly open, current will cease to flow, thus no electromagnet.
Is a circuit breaker an electromagnet?
No.
How fast does an electromagnet have to spin to produce 1megawatt?
A spinning electromagnet does not produce power without other components that you need to specify.
Is scrap metal bio degradable?
scrap metal is not biodegradable in the most common sense of the word. Scrap metal should be recycled at your nearest scrap yard. By scrapping copper aluminum and iron scrap metal, depending on the current prices, you could sell it for a hefty amount of money. currently copper is 3 dollars per pound.
What is the approximate price of steel scrap?
Scrap prices are subject to change every day, so to get the current prices visit a website like the one in link. Different scrap yards offer different prices for scrap metal so keep that in mind too. For a fair deal on your steel scrap, Id suggest you visit the SIMS facility if your town has one.
How does a scrap heap electromagnet help with recycling?
It very efficiently separates ferrous from non-ferrous scrap.
Where can i find a diagram of a scrap yard electromagnet?
I tried to find one but was unable to.
What are the benefits of recycling metals?
It brings in scrap metal into the environment.It can be reused as something else. E.g an electromagnet.
What is a scrap yard magnet?
It is a magnet which moves metal around the scrap yard. Scientific explanation = It s a big round magnet which is actually an electromagnet. This allows the magnet to be turned on then off. When turned on the electromagnet attracts any magnetic substances. This is why most cars are made of something magnetic! You can move this electromagnet around because it is a crane you pick stuff up move it and then drop it by turning the electromagnet off!
How does a scrap heap crane work?
A scrapheap crane works simply by a piece of soft iron surrounded in coper coiled coil and a electromagnet. when the switch is activated a current is sent from the battery to the electromagnet!
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.
Where are electromagnets used in industry?
An electromagnet is used in an electrical engine, but an electrical engine contains normal magnets too.
How does a car scrap heap magnet work?
Scrap Heap MagnetUsually the kind of magnet a junkyard uses is an electromagnet. An electromagnet is simply an iron core wrapped around by copper wire. Then current runs through the wire, it becomes a very strong magnet. There are other types, but I think electromagnet is the most common for car scrap heap.
What is elecotromagnet?
An electromagnet - is essentially a metal 'core' encased in wire. When power is applied to the wire, the core becomes magnetic - when the power is turned off, the magnetism is lost. Think along the lines of a crane in a scrap-yard. The crane has an electromagnet attached to its lifting arm. The operator switches on the magnet to lift a load of scrap metal, and switches it off to drop the load.
What happens to pieces of aluminum in a pile of scrap metal when an electromagnet nears the pile?
If the aluminum has iron attached to it it will be picked up by the magnet otherwise it will remain on the ground.
What does a circuit diagram for a scrap heap magnet looks like?
The cicuit at first is all conected when it is turned on then the person driving the machine will turn the engine off and the circuit will disconnect causeing the magnet not to keep hold of the metal.
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
