Steorn motor V2: Measuring the coil inductance Vs the rotor magnet angle

This experiment shows the change of the coil inductance Vs the rotor magnet position above the toroidal stator coil. I have used the Steorn motor v2 for conducting this test. I have measured the coil inductance with an inductance meter Voltcraft LCR-90…

Resonance Effects: Tesla Bifilar Coil Alternating Field Rotating a Magnetic Compass

Here’s a little illustration of an interesting phenomenon. A small magnetic compass is placed onto a Tesla Bifilar pancake coil, and the coil is driven by an alternating square wave at a frequency that…

Extreme High Voltage: TK4 MOT-DC Tesla Coil Component Overview

PLEASE DON’T ATTEMPT THIS PROJECT unless you understand HIGH VOLTAGE SAFETY. The voltages developed are LETHAL and can remain stored in the cap bank even when the equipment is not energized. An overview of…
