<h1>The Electromagnetic Interaction</h1>
<p>The electromagnetic force is the force affecting electrically charged
particles. This is the force that keeps the electrons close to the
nucleus of an atom. How do the charged particles communicate with each
other? They exchange a certain type of particle, called the
photon. This is the same particle that makes up light! Visible light,
X-rays, microwaves and radio waves are all photons, with different
energies.</p>
