Molecular rotation occurs in materials containing polar molecules having an electrical dipole moment, with the consequence that they will align themselves in an electromagnetic field. If the field is oscillating, as it is in an electromagnetic wave or in a rapidly oscillating electric field, these molecules rotate continuously by aligning with it. This is called dipole rotation, or dipolar polarisation. As the field alternates, the molecules reverse direction. Rotating molecules push, p… WebDielectric heating occurs when high-frequency electromagnetic radiation stimulates the oscillation of dipolar molecules (e.g., water molecules) in the surrounding medium at a … emergency and urgentWebMay 31, 2024 · Dielectric heating, also called Capacitance Heating, method by which the temperature of an electrically nonconducting (insulating) material can be raised by subjecting the material to a high ... emergency animal clinic bessemer al
