magnetic lines of force

[mag′ned·ik ′līnz əv ′fȯrs]
(electromagnetism)
Lines used to represent the magnetic induction in a magnetic field, selected so that they are parallel to the magnetic induction at each point, and so that the number of lines per unit area of a surface perpendicular to the induction is equal to the induction. Also known as magnetic flux; magnetic lines of flux.

As long as the copper wheel turned, its rim continually cut through magnetic lines of force and an electric current flowed continually in the wheel.
Iron filings sprinkled around a bar magnet reveal that the magnetic lines of force loop from one end of the bar to the other and are densest, or strongest, at each end.
If the rotary motion of a copper wheel cutting across magnetic lines of force can induce an electric current, then an electric current ought to be able to produce a rotary motion.
