​

Thanks for the answers​

​

But this is not what I search​

​

When I connect the audio signal to the transformer that the first coil is approximate 60 ohms (thin wire and a lot of wrapping) and the second coil have 2 ohms (thick wire and littile of wrapping) and this connected to a button loop (very thick wire with length of 50 cm)​

​

In the button loop create a magnetic field and this magnetic field I can receive from 50 cm​

​

With other button loop and then I transmit the magnetic field back to audio signal​

​

The transformer used for passive transmits voltage to amperage.​

​

I need to do an active amplifier for voltage to amperage​

​

The audio signals will amplify and will transform to very strong amperage into the bottom loop and then will create a very strong magnetic field and the system will be smaller and lighter​

​

I search after information about how to build this amplifier​

​

And search after electronic circuit sketches that can do this.​

​

 

! anybody !

 

somebody !

 

You did not post your schematic so we don't know what you are talking about.

Does your transformer have a laminated iron core?
Your primary winding has such a high resistance that most power will be wasted in the resistance. The voltage at the output winding will be the ratio of the number of winding turns minus the losses in their resistances and on the load resistance.
The current in the low voltage winding also depends on the ratio of the number of winding turns minus the losses in their resistances and on the load resistance.
