Caduceus coil

[JoeLag]

Here is my build, how do I test if it really produces scalar waves.

the magnetic field becomes minimal (you can test a led with a small coil) If its getting several feet of range its most likely a poor scalar transmitter.

If its generating scalar waves, a Wireless receiver on the other side of the room shielding in a faraday cage or similar, same setup coil as antenna. A spectrum analyzer on the RX side should find some peaks on your frequency.
