The soft-iron is a suitable material for making an electromagnet. This is because soft-iron has :(A) low coercively and high retentively(B) low coercively and low permeability(C) high permeability and low retentively(D) high permeability and high retentively |
|
Answer» Correct option is (C) high permeability and low retentively The soft iron care have high permeability. So that magnetization is large even for a small magnetizing field. Low retentivity, so that material will not retain the magnetic properties. |
