Iron is commonly used as the core metal for electromagnets due to its high magnetic permeability, which allows for stronger magnetic fields to be created. Additionally, iron is cost-effective and widely available.
Yes, scrap metal can be attracted to an electromagnet because when an electric current passes through the coil of wire in the electromagnet, it creates a magnetic field that can attract ferromagnetic materials like iron and steel.
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.
It would get larger due to the expansion of the metal (see the related links)
The core of an electromagnet should not be made from steel because steel can retain magnetism and decrease the efficiency of the electromagnet by causing residual magnetism. Instead, materials like soft iron or iron alloys are preferred for electromagnet cores as they can be easily magnetized and demagnetized.
You would want to use an electromagnet when you need the magnetic field to be controlled and easily turned on and off, such as in industrial applications like material handling or scrap metal sorting. Electromagnets are versatile as the strength of the magnetic field can be adjusted by changing the electric current flowing through the coil.

Iron is commonly used for the core of an electromagnet due to its high magnetic permeability, which enhances the strength of the magnetic field produced. Additionally, iron is a relatively inexpensive material compared to other options like cobalt or nickel.
To make a remote-controlled electromagnet, you would need a remote control system, an electromagnet, and a power source. You can connect the power source to the electromagnet through a relay controlled by the remote system, allowing you to turn the electromagnet on and off wirelessly. This setup would enable you to control the magnetic force remotely.
The compass needle would align itself with the magnetic field produced by the electromagnet. The north-seeking end of the compass needle would point towards the south pole of the electromagnet, and vice versa.
There are several places someone can purchase a metal bar. Home repair stores such as Lowe's or Home Depot would have a variety of metal bars to choose from. Another option would be to look into websites that specialize is metal materials.
It will pick up the nails the same way a bar magnet would do!
The compass needle would align itself with the magnetic field produced by the electromagnet. The north-seeking pole of the compass needle would point towards the south pole of the electromagnet, indicating the direction of the magnetic field.
