This can perhaps be visualized most clearly by taking a group of neighboring lines of force forming a slender tube: the "fluid" inside this tube flows round and round, so as the tube goes into the closed surface then comes out again (maybe more than once) it is easy to see that what flows into the closed surface at one place flows out at another. If a wire is bent into many continuous loops to form a long spiral coil, then the magnetic lines of force tend to go through the center of the coil from one end to the other rather than around the individual loops of wire.

With about 320,000 at the end of 2015 it was on track for these targets. In 1883 and 1884, while beating a path from his research lab to the patent office, he introduced the world's first economically viable system of centrally generating and distributing electric light, heat, and power. (See "Greatest Achievement?") Powerfully, instrumental in impacting upon the world we know today, even his harshest critics grant that it was a Herculean achievement that only he was capable of bringing about at this specific point in history.

This note covers the following topics: electric fields, electric potential, capacitors, circuits, magnetic fields and forces, creating magnetic fields, Faraday's law, oscillating circuits, Maxwell's equations, electromagnetic waves and nature of light.

Provided no alternating potential is applied to the grid circuit in series with an impedance the plate and grid circuits are completely symmetrical for an alternating-current component and a parallel or shunt analysis is the most obvious one. Students may be surprised to learn about the many ideas and abilities of this extraordinary person.
