Electromagnetism is the combined effect of electricity and magnetism. Every electric current creates its own magnetic field. Maxwell’s screw rule says that the magnetic field runs the same way a screw turns if you screw it in the direction of the electric current. An electromagnet is a strong magnet that is only magnetic when an…

The electromagnetic spectrum is the complete range of radiation sent out by electrons. It is given off in tiny packages of energy called photons, which can be either particles or waves. Electromagnetic waves vary in length and frequency. The shorter the wave, the higher its frequency (and also its energy). The longest waves are over…
