In heating the ferromagnetic material by induction heating, heat is produced due to_____________?
Correct answer: C. due to hysteresis loss as well as eddy current loss takingplace in the charge
- A. induced current flow through the charge
- B. hysteresis loss taking place below curie temperature
- C. due to hysteresis loss as well as eddy current loss takingplace in the charge
- D. none of the above factors
Explanation
In ferromagnetic materials below the Curie temperature, the alternating magnetic field causes both induced eddy currents and repeated magnetization, producing eddy-current and hysteresis losses. Hence both mechanisms contribute to the heat.
