Wrapping Up Electromagnets Materials

Take an ordinary iron nail, wrap it with several loops of insulated copper wire, and hook a battery to it. You now have an electromagnet—a magnet that is created when electricity flows through a wire around an iron core. By using a compass and a switch you will be able to demonstrate that the magnetic field is created when electricity is flowing through the circuit, and it disappears when the electricity is stopped. You will also be able to demonstrate the ability of the magnetic field to attract and hold iron objects such as paper clips.
