The universe is filled with the push and pull of magnetic fields. They surround every planet, star and galaxy. The magnetic field surrounding Earth protects us from the sun's rays and creates the auroras that light up the polar regions. Now you will be able to harness that power in your own corner of the universe by creating your own magnetic field.
