As a diver, I'm constantly struggling with accurate compass readings.
How much ferrous material at what distance would affect a compass? For example, would fifty pounds of steel two feet away affect the needle?
If the needle of a compass is magnetic, will the needles on two compii affect each other? At what range? Inches?
