The right hand rule: current passing through a wire produces a magnetic field around it. Hold your right hand out, palm down. Extend your thumb. The thumb points in the direction of current travel - from positive to negative - and the curling fingers correspond to the direction of the magnetic field from positive to negative around the conductor.
Lol.

True enough, which is why I said "most." I only brought it up because wire hangars are usually a lot more accessible than the piece you mentioned, however, I think that's an excellent use. I honestly can't remember the last time I changed the wiper blades on any of my vehicles, though (I live in the desert).

Electrical current flows from the negative terminal to the positive terminal.
