If you run a compass over a piece of metal, it will go crazy

Only if it has some magnetic quality. And lead will never have that.

I did a “Take Back” a couple posts earlier.

Not necessarily.

I do not know if the effect would be sufficient, but if a compass’ magnetic needle gave off a sufficient magnetic field, and you moved it over a piece of conductive metal, the moving magnetic field would, through inductance, create a current “swirl” of moving electrons in the metal, regardless of magnetism. That swirl of current will produce a magnetic field of its own, exactly opposite to that of the inducing magnetic field, and that field will interact with the field of the needle, as if you were moving a magnet by it.

Any conductive metal, put in a moving magnetic field will do that.

A metal detector is actually producing a shifting magnetic field, to simulate a moving magnet, and measuring the counter-field produced by the inductance current in the metal you are detecting. That is why it can detect other, non-magnetic metals.

Never tried it with a compass though, but I suppose if the compass has a magnetic effect strong enough to detect iron, moving it would detect other metals.
