Making Electromagnets in Science Lab

Today the students made simple electromagnets. Their electromagnets consisted of a length of conductive wire, copper, wrapped around a piece of metal, in our lab an iron nail. They created a current using a battery which allows the electron to flow through the wire. This created a magnetic field around the coiled wire, magnetizing the metal as if it were a permanent magnet. Electromagnets are useful because you can turn the magnet on and off by completing or interrupting the circuit, respectively.
