Questions
Magnetic materials used for making permanent magnets (P) and magnets in a transformer (T) have different properties of the following, which property best matches for the type of magnet required?
detailed solution
Correct option is C
For permanent magnet retentivity and coercivity must be high.For magnets in transformer hysteresis loss must be small, so both retentivity and coercivity must be low.Talk to our academic expert!
