ABSTRACT:
This invention provides a system for providing heat to a substrate in an alternating magnetic field using lossy heating particles. This invention in particular discloses an article which is a combination of a base material and lossy heating particles capable of producing the desired heat and capable of being self-regulating at a preselected Curie temperature when subjected to an alternating magnetic field. The article of this invention is adapted to be placed on a substrate in order to heat the substrate in an alternating magnetic field and is adapted to provide the removal of the particles from the substrate after the heating is completed. Preferred materials for the article of this invention are gel materials having a cone penetration of at least about 50(10.sup.-1 mm) and at least about 100% elongation. Preferred magnetic particles for use in this invention include the combination of lossy heating particles, alone or in combination with nonlossy particles for maintaining the magnetic circuit coupling while the lossy heating particles are at the Curie temperature.
