What are Protons? Protons: particles in conjunction with neutrons that make up the nucleus in atoms. These particles have wave properties. Protons are the nucleus of the simplest atom hydrogen and have a positive charge (= +e = +1.60 C 10-19C same magnitude as for the electron). Magnets produce magnetic fields, along with electric currents. Magnets have two poles, north and south. Protons are subject to the rules of magnets because of their positive charge. Like charges repel each other, while unlike charges attract. When separated out, proton are positively charged. Protons are no exception to this rule. When a magnet is incorporated, protons are attracted to the negative charge or the south-pole. Having a good understanding of WHAT protons are will allow a better conceptual grasp on how Proton Therapy works to help suffering patients.       (img1)
