WebMar 3, 2009 · It's not a permanent magnet, it's an electromagnet. When a current is passed through wire, it creates a magnetic field. The more current, the stronger the magnetic field. So electromagnets are usually made by wrapping a coil of wire tightly around a peice of iron, or other ferromagnetic material. WebOct 9, 2007 · When a car is scrapped, the different types of metals need to be sorted. A huge rotating magnet is used to sort the magnetic materials from the non-magnetic materials. Separating the materials...

How does the magnet used at a scrapyard work?

WebAug 8, 2024 · The scrap heap magnet is basically a giant electromagnet that is powered by a very large battery. It works the same way an ordinary electromagnet works. Thick insulated copper wire is wound around a soft iron core. When the current passes it becomes very strong and attracts all the magnetic materials in the scrap. Why do scrap yards use … WebThe scrap heap magnet is basically a giant electromagnet that is powered by a very large battery. It works the same way an ordinary electromagnet works. Thick insulated copper wire is wound around a soft iron core. The magnetic power of an electromagnet depends upon the current and the number of turns in the coil. maplibre github

WebThe scrap metal can then be moved around and repositioned by turning off the electromagnet. To make the electromagnet stronger we would use a large number of turns of wire for its coil and/or we would use a large current, and we would always choose an iron core.
