How does an electromagnet work in a scrapyard?
In a scrapyard when the workers need to pick up a car there is a crane with a magnet on it. So when they see a car they turn the electric magnet on so it picks up the car and they turn off the electric magnet to drop the car.
What is an electromagnet junkyard crane called?
electromagnetic junkyard crane
Can you give me an example of a simple sentence using the word electromagnet?
There is an electromagnet in that crane
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 do you get on top of the crane on scrapyard on modern warfare 2?
I don't think you can but I'm not completely sure
How does a crane use electromagnet?
A crane or junkyard crane uses an electromagnet to pick magnetic items up. The crane controls the electromagnet by using a a circuit that has a wire wrapped around a piece of metal that can be magnetized that's at the end of the crane's arm. When the circuit completes, the metal at the end of the cranes arm gets temporarily magnetized. When the current stops, the metal get demagnetized and can't pick things up anymore.
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.
An electromagnet would most likely be used as a what?
A device on the end of a crane to lift cars and junk
How can turning on the electricity allow the iron crane to pick up the car?
Connecting the electricity will activate the electromagnet.
Why does a crane use an electromagnet instead of a permanent magnet?
So that the load can be dropped by turning off the current.
How is electromagnet the same as permanent?
An electromagnet is only magnetic while current is flowing through the coils. A permanent magnet is always magnetic, and does not need electricity. An example of an electromagnet at work is in a metal scrape yard, where a large electromagnet is used by a crane operator to lift ferrous metals into a crusher (scrapped cars, for instance). The metal drops into the crusher when the electricity is switched off by the crane operator. Therefore, they are only really similar when both are magnetised.
