A ferrite core has less eddy current loss than an iron core because_______________?
Correct answer: A. ferrites have high resistance
- A. ferrites have high resistance
- B. ferrites are magnetic
- C. ferrites have low permeability
- D. ferrites have high hysteresis
Explanation
Ferrites have much higher electrical resistivity than ordinary iron, so circulating eddy currents and the resulting loss are greatly reduced. Their high resistivity is especially useful at higher frequencies.
