How Does a Scrap Heap Magnet Work?

Answer

The scrap heap magnet is a heavy electromagnet. On a soft iron core thick insulated copper wire is wound. As the magnetic power of an electromagnet is dependent upon the current, number of turns in the coil, the copper wire should be able to withstand heavy current and the more the number of turns, the more the magnet 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 demagnetised and all the magnetic materials will fall down from it.

Scrap magnets operate on a concept called electromagnetism. This is where a magnet is formed when an electric current is passing through a winding of wires over a magnetic metal core such as iron or steel. The magnets can then be used to remove metal pieces from substances.
Scrap heap magnets work by use of coiled wires on a loop whereby electric current is passed through creating a magnetic field. The magnetic power of an electromagnet is dependent on the current and the more the number of coils, the heavier the current therefore creating a very strong magnetic field.
A scrap heap magnet is a large, heavy electromagnet that is on a soft iron core where a thick insulated copper wire is wound. The magnetic power of an electromagnet depends on the current and the number of turns that are in the coil since the copper wire should be able to handle heavy current. The more the number of turns, the stronger the magnetic strength of the field. When the current passes, the magnet becomes strong hence attracts all the magnetic materials in the scrap then when the current flow is stopped, the magnet becomes demagnetized and the scrap metals fall off or down. The operating switch is near the operators cabin. The crane is brought near the scrap then the magnet is switched on then the scrap is attracted to the magnet then the operator moves the crane then switches off the magnet and after demagnetization, the scrap falls off on the necessary location it being carried to.
A scrap magnet is a heavy electromagnet that usually attracts all the metallic materials in a scrap metal yard when current is passed through it. Using a soft iron core, thick insulated copper wire is wound around it and a heavy electric current is then passed through it. When the current passes, the core becomes a strong magnet and attracts any metallic object in its path.
It can attract large and heavy objects such as cars, lorries, metal chairs and many more items even though these items need to be constructed of iron, steel, cobalt or nickel, depending on the type of metal or metals that were used to make these items.
The scrap heap magnet is nothing but a heavy electromagnet. On a soft iron core 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 withstand heavy current and more number of turns create very strong magnetic field. When the current passes it becomes very strong and attract all the magnetic materials in the scrap.
A scrap heap magnet is a kind of heavy electro magnet that uses a thick soft iron core that is insulated with copper wire. As current passes through the copper wire it creates a strong magnetic field thereby attracting magnetic materials in the scrap.
