System and method for reducing crosstalk between workcoils in induction heating applications

A system comprising:

• a roll comprising a conductive material, the roll configured to rotate about an axis and having a diameter and a direction of rotation;
• and
• multiple induction heating workcoils each configured to induce one or more magnetic fluxes within the roll to generate one or more electrical currents within the roll;
• wherein each of the induction heating workcoils is oriented so that a mean magnetic flux induced by the workcoil is oblique to the roll's direction of rotation;
• and
• wherein each of the induction heating workcoils comprises a core having a shape that is not substantially dependent on the roll's diameter.

A method comprising:

• placing multiple induction heating workcoils in proximity with a roll;
• and
• generating multiple electrical currents within the roll using the induction heating workcoils;
• wherein each induction heating workcoil is oriented such that a mean of one or more magnetic fluxes induced within the roll by the workcoil is oblique to the roll's direction of rotation so as to reduce inductive coupling between the induction heating workcoils.
