Question

For making an electromagnet, the most suitable material is ??

Answer 1

The answer is soft iron

Materials used for making eletromagnets should have best magnetising and demagnetising property. Among stainless steel, silver , soft iron and Nickel , soft iron has best magnetising and demagnetising property.
Therefore, soft iron is most suitable

Answer 2

For making an electromagnet, the most suitable material is soft iron
or Laminated silicon steel.
Because they should have the property of magnetising ( magnetic properties)and demagnetising( process of removing magnetization). moreover it should should be good conductor of electricity and heat which will prevent from any electric shock or circuit.
so soft iron or laminated silicon steel is best suited for it.
