Fluxtrol

Fluxtrol flux concentrators help induction heating users achieve increased productivity by focusing heating on critical areas only (via control of magnetic fields) and thus greatly reducing time to temperature. In addition, more power is transferred into the selected area of the workpiece with the same coil current. Precision heating occurs exactly where it should, improving workpiece quality, production output and process efficiency. And because our proprietary soft magnetic materials reduce energy consumption, as well as, minimize distortion thus reducing scrap, they are environmentally friendly. (Example.pdf)
Fluxtrol materials are soft magnetic composites made of magnetic powdered metals and dielectric binders by compacting at high pressures with subsequent thermal treatment.  They are used for magnetic flux control (concentrating, shielding or modifying), essentially capturing the alternating magnetic field and re-directing or focusing it to the desired area of the workpiece (or part). 
Magnetic Flux Control is a generic term for modification of induction coil magnetic flux by means of installation of magnetic templates (magnetic flux controllers).  Magnetic controllers may significantly change magnetic field pattern and coil parameters;  their application must be considered as a part of the whole induction system design.
