How does the saturation levels limit the design?(a) saturation levels

1.	How does the saturation levels limit the design?(a) saturation levels decrease the flux density(b) saturation levels increase the flux density(c) saturation levels provides no flux density(d) saturation levels provide very high flux densityI have been asked this question in a job interview.This interesting question is from Design of Machines, Limitations in Design in division Fundamental Aspects of Electrical Machine Design of Design of Electrical Machines
Answer» The CORRECT choice is (d) saturation LEVELS provide very high flux density Explanation: The MAXIMUM ALLOWABLE flux density to be used is determined by the saturation levels of ferromagnetic materials. The saturation levels provides high flux density which results in high COST.
