In this article I'll discuss a more recent experiment investigating the phenomenon of mutual inductance coupling as it applies to inductor coils used ... chose 2 virtually identical 3mH air core ...

Making your own inductor may seem daunting. You will have to answer a few questions such as: “what type of core will I use?”, “how many turns does my coil need?”, or “how do I calculate ...

A Tesla coil is made of two ... and has no energy left, the inductor reaches its maximum charge and sends the voltage into the spark gap (basically a gap of air between two electrodes).
