Heating Effect of Electric Current: Concept, Joule

WebIn general inductors do not generate heat because the energy is stored in the magnetic field then released again. Only a very small portion of that energy is lost to the inductor's internal resistance. The rest of it will be generated by $P_l=i^2 * (R+R)$ where the inductor is the current source with the switch is opened. – user6972 WebOften the increase in temperature is caused by an increase in current.
