Point out the wrong statement. Magnetic leakage is undesirable in electric machines because it___________?
Correct answer: A. lowers their power efficiency
- A. lowers their power efficiency
- B. increases their cost of manufacture
- C. leads to their increased weight
- D. produces fringing
Explanation
Leakage flux does not directly dissipate power, although it reduces useful flux and can worsen machine performance. It can require more material, increase weight and cost, and contribute to flux spreading or fringing.
