A keeper is used to_____________?
Correct answer: D. provide a closed path for flux
- A. change the direction of magnetic lines
- B. amplify flux
- C. restore lost flux
- D. provide a closed path for flux
Explanation
A keeper is a piece of soft iron placed across the poles of a permanent magnet to complete the magnetic circuit. This provides a low-reluctance closed path for flux and helps prevent loss of magnetism.
