An iron core and copper wire (that is coated with an insulator) are used all the time to make electromagnets.
The springy pieces of metal or carbon that make contact with the commutator's contacts in an electromagnet are known as brushes. Brushes are responsible for delivering electrical current to the commutator, allowing the electromagnet to function as intended.
An electromagnet operator can release metal attached to the electromagnet by turning off the electric current flowing through the electromagnet coils. This de-energizes the electromagnet, causing the magnetic field to dissipate and the metal object to fall off.
To make an electromagnet, you would need a metal core wire (such as iron or steel) and a power source, such as a battery or electrical current. The metal core wire is wrapped around a core material and the electricity passing through the wire creates a magnetic field around the core, resulting in the electromagnet.
The size and length of the metal core can affect the strength of an electromagnet. A longer core will generally result in a stronger magnetic field, but the material and diameter also play a role. The core should be made of ferromagnetic material like iron or steel for best results.
An electromagnet attracts metal because when an electric current flows through a coil of wire, a magnetic field is created around it. This magnetic field interacts with the metal object, inducing a temporary magnetic force that pulls the metal toward the electromagnet.

The role of an electromagnet is to provide us withrecycled materials. The electromagnet is what picks up our heavy metal bits and bobs and moves it or drops it from a certain height so that the metal breaks and can be used again to make another car .

An electromagnet attracts metal because when an electric current flows through a coil of wire, a magnetic field is created around it. This magnetic field interacts with the metal object, inducing a temporary magnetic force that pulls the metal toward the electromagnet.
The switch is turned on to activate the electromagnet, and metal is attracted. Turning off the switch stops the electromagnet from working, and metal is no longer attracted.
To make an electromagnet toy, you will need a battery, insulated copper wire, a small metal rod or nail, and a switch. Wind the copper wire around the metal rod tightly, leaving ends free. Connect the wire ends to the battery terminals with the switch in between and when you turn on the switch, the current will flow through the wire creating a magnetic field, turning it into an electromagnet.
