Pregunta	Respuesta
Why are split rings used in a motor?	1. Turn continuously 2. Keep spinning in one direction
Why do we use the F.L.H. Rule?	To figure out where either Force, Magnetic Field Direction, or Current is facing. Remember by: F.B.I.
What does Lenz's law state?	1. A current is induced in a closed conducting loop, only when the magnetic flux, in the loop, changes. 2. Direction of induced current is such that the induced magnetic field always opposes the change in flux.
