Abstract: Systems and methods of hot forming a metal blank include receiving the metal blank at a heater and positioning the blank adjacent a magnetic rotor of the heater. The systems and methods also include heating the metal blank through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal blank such that the metal blank is heated.
