Electron Discovery (PowerPoint)
... At the end of the 19th century it was known that when a very high voltage was applied between the cathode (negative electrode) and the anode (positive electrode), the end of the gas filled tube would glow. A hole in one or more screens restricts the glow to a tiny spot. It seemed as if something bei ...

Electricity and Magnetism
... Electromagnets Magnetic field is present only when current is flowing in the wire coil Increase strength of the magnetic field by adding coils to the wire or increasing the current flowing through the wire Magnetic properties of electromagnets can be controlled by changing the electric current flow ...

... By the end of the 12th grade, students should know that Electromagnetic forces acting within and between atoms are vastly stronger than the gravitational forces acting between the atoms. At the atomic level, electric forces between oppositely charged electrons and protons hold atoms and molecules ...
