High Frequency Variometer Coils
Experimental Wireless Coils, Diathermy Coils, Tesla/Oudin Coils
Left: High Frequency Tesla / Oudin Coil; Right: Diathermy / Thermo-Penetration Coil
Alternately: Left: Resonator, Right: Oscillator. In this way the intensity of the Tesla circuit can be varied by swinging the angle
one way or the other without breaking the circuit.
Tangential wire for the output - made with silicone and wire-wrap!
Alternately still the coils can be demonstrated in a flat position, one coil being used to detune the other!
Appearance of coils folded together. Maximum output when used as an Oscillator / Resonator.
