Abstract
A rotating magnet heater for metal products, such as aluminum strip, can include permanent magnet rotors arranged above and below a moving metal strip to induce moving or time varying magnetic fields through the metal strip. The changing magnetic fields can create currents (e.g., eddy currents) within the metal strip, thus heating the metal strip. A magnetic rotor set can include a pair of matched magnetic rotors on opposite sides of a metal strip that rotate at the same speed. Each magnetic rotor of a set can be positioned equidistance from the metal strip to avoid pulling the metal strip away from the passline. A downstream magnetic rotor set can be used in close proximity to an upstream magnetic rotor set to offset tension induced by the upstream magnetic rotor set.
