Hello,
I found a circuit (transmitter) design that would create an oscillating magnetic field. Another circuit (receiver) would pick the induced voltage up and amplify it.
Now as I understand it, the oscillating part has only positive voltage. But in the receiver part they use a recitfier. Why would you need this if the induced voltage is only ever positive ?
thanks,
