Which statement correctly describes how to reduce both hysteresis loss and eddy current loss in magnetic cores?

Which statement correctly describes how to reduce both hysteresis loss and eddy current loss in magnetic cores?

• A. Hysteresis loss depends on material and frequency; eddy current loss depends on conductivity and thickness; reduce with laminated cores, lower conductivity materials, higher resistivity, or grain-oriented steels.
• B. Hysteresis loss depends only on temperature; eddy current loss depends only on geometry.
• C. Hysteresis loss depends on mass of core; eddy current loss depends on operating voltage.
• D. Hysteresis loss is independent of frequency; eddy current loss is independent of conductivity.

Answer: (A)
