How can hysteresis loss be reduced in design?

Use a solid core with no gaps and a high flux density
Use a low-hysteresis core alloy and a low flux density
Add more primary turns only and keep the same core
Use thinner winding wire and keep the same core

Show answer

Correct answer: Use a low-hysteresis core alloy and a low flux density

A low-hysteresis alloy and a large core cross-section (low flux density) both cut this loss.
