Making An Electromagnet

By Go-Repairs

The wire produces a weak magnet field when current flows through it.
By coiling the magnet wire we concentrate the magnetic field
Coiled enamelled copper wire makes a weak magnet

Step 1

Simply running current through a wire produces a weak magnetic field. But this is usually too weak to give us visable results. By coiling the wire closely we amplify the magnetic influence which gives us visable results. The closer these windings are the better the electromagnet will be.
