Usually 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.

∙ 14y agoA scrapheap magnet is a large electromagnet. It can be turned on and off. They can turn it on. It picks up scrap in one place. It holds the scrap as it moves it from one pile to another or one place to another. Then they turn it off and it drops its load. They can do that several times. Finally it moves it to the back of a truck or train car to be hauled to a recycling plant.

It transports random scraps of metal from one place in a junkyard to another place in a junkyard.

Why would they use a magnet in a scrap yard?
To move heavy scrap metal from place to place. You are able to flatten scrap metal with some magnets, this enables you to pick up more. My magnet weighed in at 5 tons, therefore can easily crush a car and pick up multiple flattened cars. These types of magnets are very powerful and can penetrate through multiple layered vehicles if they have been crushed, otherwise to hover a magnet over a car in its original un-crushed condition would not be a sufficient enough magnetised area (just the roof on its own) for the magnet to hold the weight of a car. I hope this helps to explain your question.
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.
Why does a fan need coil and magnet?
Not all fans do need a coil and magnet - there are hand fans, punkah walla fans belt driven fans (as in your car) and Stirling engine fans that I can think of that do not need a coil or a magnet. It is only electrically driven fans that require a coil and magnet because they work on the principles of electromagnetism.
Does a vacuum cleaner need a magnet to work?
Some kind of magnet or magnetic field is necessary for a motor to operate. Alternating current vacuum cleaners (that plug into the wall) have motors with electromagnets. Direct current vacuum cleaners (that plug into the car's cigarette lighter socket) have motors with permanent magnets.

0 work is force times movement.
What are facts about the scrap yard magnet?
A scrapyard magnet is a large magnet that attracts materials such as colbolt, iron, nickel. It can be turned on and off, and when you turn off the magnet it drops all the scrap, it is taken by truck or train car and then it goes to a recycling plant.as it moves it holds scrap and takes it to another pile.

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.
Can a magnet move a car?
A magnet can move a car, if the magnet is strong enough.
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 much money can one expect to get for a scrap car?
There is not an average dollar amount that one can expect to get for a scrap car. The dollar amount depends mostly on how large the car because of the scrap metal.
