b) Why do we use iron for making an electromagnet and not steel ?

Who will answer 1rst correct answer will be the Brainliest.

Answer 1

1). above image a). is stronger magnet because it is prepared from the soft iron core and that iron is a work as a magnet and it is Megnet in which the magnetic field lines rendomely direction and it keep solenoid than M. F lines one direction..... when pass the current throughout the solenoid.....
