__________is extensively used for those portions of magnetic circuit which carry steady flux and need superior mechanical properties ?
Correct answer: B. Cast steel
- A. Grey cast-iron
- B. Cast steel
- C. High carbon steel
- D. Stainless steel
Explanation
Cast steel is selected for magnetic-circuit sections carrying steady flux when high mechanical strength is important. Grey cast iron is easier to cast but is more brittle and mechanically weaker.
