Yeah, but coat hangers are part of HER domain (I don't mean my daughter). She never goes near windshield wipers or the man cave in my garage. Besides, I don't think a coat hanger would work nearly as well in the hand grip situation or the motor brushes. They're coated with laquer which I wouldn't want in my gasoline.
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.
