Answer 2

I remember that a scrap heat metal magnet works because it has an electromagnet inside it. The electromagnet has a soft iron core (so that when it can be turned on and off), a coil of wire with lots of turns (to increase the strength of the magnet), and the voltage is very high (also to increase strength.

A scrap heat magnet is a big crane in a junk yard that can pick up lots of scrap metal, e.g. a car or parts of a car. It can pick up a car and put it in a crusher, like on that advert of not paying your car tax.
What does a scrap heap magnet do?
It picks up all the magnetic metals and separates them from the non-magnetic metals
The "SCRAP HEAP MAGNET" is nothing but a heavy electromagnet. On a soft iron core (because, there should not be any retentivity) thick insulated copper wire is wound. As the magnetic power of an electromagnet is depending upon the current, number of turns in the coil, the copper wire should be able to withstand heavy current and more number of turns will create very strong magnetic field. When the current passes it will become a very strong magnet and will attract all the magnetic materials in the scrap. When there is no current the core gets dememagnetised and all the magnetic materials will be falling down from it. This arrangement is fitted at the tip of the cable of a crane and the operating switch will be near the operator’s cabin. The crane will be brought near the scrap, and the operator switch the magnet on and all the scrap will be attracted by the magnet. Then the crane will be turned to another place the operator switches the magnet off. All the scraps will be falling down.
Instead of a soft iron core (less retentivity) another material with high retentivity is used even after switching it off the scrap will not be falling down.
A scrap heap magnet can attract heavy and large objects like cars lorries metal chairs and many more thing but they have to be made out of iron, cobalt, nickel or steel well sometime depending on what metals or used to make it.

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.

i love you. (:

Answer 6

it is a magnet which can be turned on and off, just by opening and closing a switch.

Answer 7

a scrap heap magnet is a large magnet wrapped in coil it cn pick up all sorts of things e.g cars , lorries ,metal chairs
