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…

Magnetic Resonance Amplifier 3: Capacitor Instead Of Piezo Element

Please watch the first two videos first. Here I take the Piezo element out of the circuit and replace it with a capacitor of similar value. The circuit behaves nearly the same as before…

Magnetic Resonance Amplifier 4: Ferrite Core Without Magnets

Please watch the first three videos first. Schematics and further explanations are found in them. Here I’ve made another transformer using half of a TV CRT horizontal deflection yoke ferrite. I wound it with…
