Scrap heap magnets are basically electromagnets. Electromagnets are magnets that can be turned off and on. When they are turned on, the circuit inside them, (which normally consists of a battery, a switch, coiled wire and an iron rod) switches on. The iron rod inside the coils of wire is magnetized once the switch can be on or off. Mechanically an electromagnet is relatively simple. As soon as you apply a small electric current it becomes magnetized. The copper wire produces a magnetic field around the core just like any other magnet. The advantage is that it can be turned on or off.
The only magnetic elements are iron, cobalt and nickel. This means that electromagnets can only attract those metals. They can also attract steel. This is because it is mainly made of iron. This is useful because it helps sort the metals into allocated locations. However they cannot pick up paper, wood or any other metal that is not magnetic, or made out of iron, cobalt and nickel.
Scrap Heap magnets work by a very simple but effective circuit board which is in them. The circuit board includes:
- A switch (To turn the electromagnet on/off)
- A battery (To power the electromagnet so there is a current flowing through it)
- A iron rod (This is the component that is magnetized.)
- Coiled wire around the rod (the current)
When a scrap heap magnet is turned on by the switch, the iron core is magnetized because of the current flowing though it due to the coiled wire and battery. This makes it magnetized and it is able to pick up any metals that are magnets and its able to place them in their designated areas in the scrap heaps.

∙ 13y agoIt is an electro magnet. Power on and you have a magnet, power off and the magnetic field is gone and the scrap falls.

What can a scrap heap magnet pick up?
metals containing iron
How do you call the magnet that is used to pick up cars in a scrapyard?
It is simply called a scrap magnet. Ohio Magnetics and Walker both manufacturer scrap magnets.
What do scrap heap magnets repel?
The strength of any electromagnet changes when the current (amperes) or the number of 'turns' of wire in its wire coil changes. Increasing either of them makes the magnet stronger.
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.
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 can move on a scrap heap magnet?
well basically anthing that is made out of metal and steel, will move on a scrap heap magnet.
Does steel attract a scrap heap magnet?
A scrap heap magnet attracts steel - but not steel with a high chromium or nickel content
What magnet is used for scrap heap magnet?
They are used everyday to move scrap iron around the scrap yard...
How can the strength of a scrap heap magnet vary?
The strength of a scrap heap magnet vary depending on the strength of the current or number of "turns" in its primary coil. Increasing either or both of these makes the magnet stronger.
How a scrap heap magnet works by using a picture?
With your MIND.
Can scrap heap magnets pick up cobalt?
Yes, a scrap heap magnet works in the exact same way as a normal magnet but on a large scale. Iron, Cobalt and Nickel are all magnetic elements.
What metals are attacted by a scrap heap magnet?
A magnet is attracted by metals containing iron in their makeup, primarily steel.
Described simply how the scrap heap magnet works?
the magnet is just a large iron disk that, when activated will become magnetic. this is used for picking up objects
What doesnt a scrap heap metal magnet attract?
Anything without iron in it, and some iron alloys such as stainless steel.
What materials can a scrap heap magnet attract?
Mostly Ferrous metals (alloys containing iron) but also Nickel, Cobalt and Gadolinium.
What can't a scrap heap magnet do?
pick up aluminum, copper, brass, plastics, cardboard, etc. (non-ferrous material)
How does a car scrap heap magnet work?
Scrap Heap MagnetUsually 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.
