* A conductor that can be shaped into a coil. Copper wire, for example. * An isolator that keeps the conductor's threads isolated from each other, thus forcing the current through all loops of the coil. * An electric current through the coil. * Typically, but not necessarily, a ferrite core to bundle the magnetic field.

To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
To make an electromagnet, you need a coil of wire and a source of electrical current. When the electrical current flows through the wire coil, it creates a magnetic field, turning the coil into a magnet.
Every thing except a conducting wire, battery and a soft iron core is not needed for making an electromagnet
The electromagnet can be turned on and off depending on whether it's needed or not.
how to make road rail signal using electromagnet
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.

To make an electromagnet rotate, you can place it in the proximity of a permanent magnet. When a current flows through the electromagnet, it interacts with the magnetic field of the permanent magnet, causing the electromagnet to rotate. This setup can be used in devices like electric motors and generators.
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.
To chew on it.
To make an electromagnet stronger, you can increase the current flowing through the coil, increase the number of turns in the coil, or use a material with high magnetic permeability as the core of the electromagnet, such as iron.
