Needs no battery....THE COIL SHALL BE 1inch in diameter and 100 windings. The capacitor must be adjustable. R shall be an high Resistance earphone with at least 3kOhm. Sorry, but this easy curcuit app is good but too many things still missing!!!

To model a speaker put a resistor and an inductor in series. To model an antenna use a very small capacitor and an AC voltage source. To model a ferrite antenna or a ring antenna use a AC source an a transformer with very low coupling coefficient. Its also more accurate to give your LC resonators a small internal resistance. For exotic parts like vacuum tubes you have to model them with the controllable current source. It's hard I know but almost anything is doable with replacement circuits. Except maybe spark gaps and neon lamps because they have a hysteresis, I don't know.

I do Hope that this Toy app will grow.
