At the following link I have arranged 157 videos in an order that will take you from vectors to electromagnetic waves. Many of the videos come from this channel but a few from another private channel I have. On some Browsers you may have to copy and paste the links

There are about 50 demonstrations to illustrate concepts. These demonstrations are built from ordinary items, many you might find around your (house, paper clips, batteries, magnets), at a hardware store, or on-line. Details of constructing the demonstrations are included. Examples are demos of electrostatic and electromagnetic induction, construction of a battery, simple motors, generation of magnetic fields from current carrying wires, a simple ac generator, construction of a loud speaker from a paper cup, magnetic braking, demonstration of Young’s double slit experiment, Spark coils, etc.
