Hello,
I bought an electronics kit for my 12 year old brother (and perhaps a little for myself too...) for building a crystal radio.
I would like to understand what's going on when I tune the radio, so that I can explain it to him. It's a simple setup, where changing the position of a ferrite rod within a coil of wire does the tuning, but how does that work?
This circuit diagram is very similar, but the design I have does not make use of a resistor.
Any help would be appreciated!
P.S I have an understanding of physics akin to A-Level
