Answer:
Induction heating is the process of heating electrically conductive materials like metals by electromagnetic induction, through heat transfer passing through an induction coil that creates an electromagnetic field within the coil to melt down steel, copper, brass, graphite, gold, silver, aluminum, and carbide.
The "<em>lb/s² </em>" is not a valid unit of work.
Each of the others is (a unit of force) x (a unit of distance) which is pretty much the definition of work.
Static electricity can be an alternating current.
