1. A heating system, comprising:
a magnetic heating apparatus for heating a metal article moving in a downstream direction, wherein the magnetic heating apparatus includes one or more heaters for inducing a tailored temperature profile in the metal article, wherein each of the one or more heaters comprises a first magnetic rotor and a second magnetic rotor, wherein each of the first magnetic rotor and the second magnetic rotor contains at least one magnetic source and is rotatable about an axis of rotation that is perpendicular to the downstream direction and parallel to a lateral width of the metal article to generate changing magnetic fields through the metal article,
wherein the first magnetic rotor is laterally positionable with respect to the second magnetic rotor to be laterally offset from a centerline of the metal article by an offset distance.
