    Making a crude radio (Difficult/Long)

    I have L=NΦ/i as it was given. To find the area for Φ=AB, if the coils are touching, then essentially it becomes a long cylinder of diameter D. And for B the diameter for the coils is D?

    Making a crude radio (Difficult/Long)

    gneill, thanks for the reply! My professor handed us this problem with a corresponding diagram and the equation for L with respect to the solenoid inductor. Forgive me if I'm wrong, but in this question, referring to the solenoid inductance, I don't have to worry about the current passing...

    Making a crude radio (Difficult/Long)

    Homework Statement Suppose you are stranded on an island and need to make a radio so that you can get weather updates. You know that weather updates for your general area can be found on short-wave radio within the frequency range f-low to f-high . Also, you manage to scavenge some thin...
