Rotating magnet heat induction

A heating system comprising:

• a magnetic heating apparatus configured to heat a metal article moving in a downstream direction along a passline through the heating system, wherein the magnetic heating apparatus comprises one or more heaters configured to induce a tailored temperature profile in the metal article, wherein each of the one or more heaters comprises:
• a magnetic rotor comprising at least one magnetic source, wherein the magnetic rotor 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;
• and
• an auxiliary magnetic heating apparatus configured to heat the metal article moving in the downstream direction, wherein the auxiliary magnetic heating apparatus comprises one or more auxiliary heaters, wherein each of the one or more auxiliary heaters comprises:
• an auxiliary magnetic rotor comprising at least one magnetic source and rotatable about an axis of rotation, wherein the auxiliary magnetic rotor is configured to provide localized heating of a sub-area of the metal article less than an entire area across the lateral width of the metal article.
