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.

∙ 15y agoThere are at least two compelling reasons to use an electromagnet in a scrap yard: 1. A large permanent magnet would be more expensive, and 2. Letting go would be MUCH harder! (So, just to be clear, scrap yards use electromagnets because they can be turned off when it is desired to let go of something that has been picked up. It can be extremely difficult to remove a metallic object from a high intensity permanent magnet!)

∙ 8y agoMagnets are used to lift the steel body work and assorted car parts rather than a "grab" crane. If the magnet was peranent the metal could not be released for off lading. An electro-magnet can have it power source turned off effectively shutting down the magnet and thus dropping the metal it had collected.

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!
What is the difference between a yard of soil and a cubic yard of soil?
"A yard of soil" is a shorthand notation for a cubic yard of soil. They are equivalent.

What is a scrapyard magnet?
a scrap yard magnet is an electro magnet used to pick up bits of metal. this is used because it can drop the metal because it can be turned on and off
What are the benefits of using an electromagnet rather than a bar manet?
An electro-magnet can be switched on & off - a bar magnet is 'permanent' Think of a scrap-yard. If the magnet they use to pick up huge quantities of metal were permanent, they'd have to manually remove every piece. With an electro-magnet, they simply turn the power on to pick up a load, and off when they want to release it. You can make your own electro-magnet with a battery, some wire and a large nail.
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.
What advantages does an electromagnet have from a perminant magnet?
An electromagnet can be turned "off" and "on". It was one of the great benefits verses a permanent magnet. If you'll watch video of a salvage yard, you will notice they hoist huge electormagnets to pick up scrap metal, and then cut the magnetism so that they can drop the debris in a desired location
What is a scrap crane?
A scrap crane is a crane (mobile or EOT -electric overhead traveling) in a scrap yard most commonly steel scrap. The applicaton I use is a EOT crane with a magnet. It loads steel scrap into a ladle which goes into a electric arc furnace.
What type of magnet can be controlled by adjusting the flow of electric current such as might be used in a scrap yard to pick up and then drop large pieces of metal?
An electro magnet.

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.
