Question
The matrials sutiable for making electromagnets should have
Options
A.high retentivity and low coercivity
B.low retentinity and low coercivity
C.high retentivity and high coercivity
D.low retentinity and high coercivity
Solution
Elctro magnet should be amenable to magnetsation and demagnation
∴ retentivity should be low and coercivity should be low.
∴ retentivity should be low and coercivity should be low.
