Step 5Circuits
These three pictures I have posted are of the circuits that I used. I have also posted a third picture of a theoretical circuit (has not been tested so i am not sure if it works) which turns the received energy into DC so you can hook it up to your favorite electronic device, iPod, cell phone...
Primary Coil-The function generator is the Main circuit of the primary, but you can easily buy it from the link posted earlier. Alon with the magnet coil.
In the Secondary Coil Diagram, the only capacitor is a 0.02 uF as I explained why.

are they the same? or you made it, and did u use any enamel coating or varnish for the same, or is it just the Magnetic core wire?
Congrats!
well I have 2 things to ask, if you can answer:-
1>What is the use of Signal generator / or the Circuit u have attached, cant u use the stereo /mono output from the soundcard using a software like audio toolbox?
2>and what is the Amperage you are getting at the output side?
how do you calculate regarding how much you need at the output?? any formulas.
suppose I need for a mobile to charge with input of 5V dc, and 550mA?
so, then how do i build this up?
Thanks in advance
seems to me like all this really is just a transformer ripped apart (with some obvious changes), but the principle is between this and a transformer is essentially the same.
good work tho
if it possible to send me the complete primary circuit and to describe the elements used in this circuit(simulation).
thanx Mr. tanmanknex
Effect of frequency
The time-derivative term in Faraday's Law shows that the flux in the core is the integral of the applied voltage. Hypothetically an ideal transformer would work with direct-current excitation, with the core flux increasing linearly with time. In practice, the flux would rise to the point where magnetic saturation of the core occurs, causing a huge increase in the magnetizing current and overheating the transformer. All practical transformers must therefore operate with alternating (or pulsed) current.
Transformer universal EMF equation
If the flux in the core is sinusoidal, the relationship for either winding between its rms Voltage of the winding E, and the supply frequency f, number of turns N, core cross-sectional area a and peak magnetic flux density B is given by the universal EMF equation
The EMF of a transformer at a given flux density increases with frequency. By operating at higher frequencies, transformers can be physically more compact because a given core is able to transfer more power without reaching saturation, and fewer turns are needed to achieve the same impedance. However properties such as core loss and conductor skin effect also increase with frequency. Aircraft and military equipment employ 400 Hz power supplies which reduce core and winding weight.
Operation of a transformer at its designed voltage but at a higher frequency than intended will lead to reduced magnetizing current; at lower frequency, the magnetizing current will increase. Operation of a transformer at other than its design frequency may require assessment of voltages, losses, and cooling to establish if safe operation is practical. For example, transformers may need to be equipped with "volts per hertz" over-excitation relays to protect the transformer from overvoltage at higher than rated frequency.
Knowledge of natural frequencies of transformer windings is of importance for the determination of the transient response of the windings to impulse and switching surge voltages.
