The magnetism left in the iron after exciting field has been removed is known as____________?
Correct answer: B. residual magnetism
- A. permeance
- B. residual magnetism
- C. susceptance
- D. reluctance
Explanation
When the magnetising field is removed, the remaining magnetism is called residual magnetism or remanence. Permeance and reluctance describe how easily a magnetic circuit carries flux, not retained magnetism.
