I want to transmit a song through inductive button loop to amplifier
I need to build amplifier that take the audio signals to cause an electric current flow into a button loop with diameter of 50 cm in a sufficient strength that generate a magnetic field that can receive the button loop that have some distance from the transmitter.
I understand that the magnetic field depend on the current strength that pass into the button loop and I need to build an amplifier that take the audio signals and amplify the current
What kind of amplifier I need ?
I want to learn this subject and I search after sites that explain this.
I search after electronics circuit that do this current amplify
The button loop was build with transformer but the magnetic signals are weak and I need to amplify the active current

Hello,

Do you have the current schematics?
With the schematics at hand we can have a look how to modify it.

Some concert halls used an inductive loop around the room and deaf people wore an inductive receiver that had very high gain.
