what is the amplitude of 169kHz signal?????

now try it with 120 miles away

Can you please provide me the details of wire and capacitor connected in parallel to both of the coils? What are it's values???

@MadScientist1011 To creat a resonant freq you can use the formula one over two pi square root lc l being inductance and c being capacitanceto calculate it

good but bad

My electric tooth brush charger circuit works on this principle and at work I used this method to test some alarms which had inductors in them.

You're missing a capacitor on the reciver coil, I use an air-variable capacitor for fine tuning on mine. Put the coil at the other end of your house then just using a frequency generator you can tune into the resonant frequency of that coil and watch the neon light up. Then measure your input and output to see if you'd picked up extra energy from your local environment. I just finished building a transverse receiver today with a small coil and a long antenna connected to a 316s steel sphere.

wow you guys have no idea what you are talking about, "wireless transfer" has been here since the first transformer was invented, learn more from transformers so you know what i'm talking about. REAL wireless transfer should reach high distances and shouldn't involve coils, since coil "wireless transfer" has much energy loses, thats why is used in transformers

what is the cap used? |
