The behavior of electrically charged particles Like charges repel each other, unlike charges attract Behavior of moving charge in magnetic field A charged particle moving though a magnetic field will feel a force perpendicular to the plane described by the velocity vector and magnetic field vector This deflects the moving charged particle according to the " right hand rule " (based on a positive charge) A negative charge will be deflected in the opposite direction Cathode rays and electrons Electrical discharge through partially evacuated tubes produced radiation. This radiation originated from the negative electrode, known as the cathode (thus, these rays were termed cathode rays) . The "rays" traveled towards, or were attracted to the
