Dielectric heating is an industrial method employed for heating of: Correct Answer Insulating materials

Dielectric heating is an industrial method employed for heating of insulating materials.

When nonmetallic materials i.e. insulators such as wood, plastics and glass are subjected to high voltage alternating electric field, the atoms get stresses and due to interatomic friction caused by the repeated deformation and the rotation of atomic structure, heat is produced. This is known as dielectric loss.

The dielectric loss in insulators corresponds to hysteresis loss in ferro-magnetic materials. This loss is due to the reversal of magnetism or magneto molecular friction. These losses are developed in a material to be heated.
