Which of the following correctly explains why soft iron is proffered to steel in electromagnets? i. soft iron is more readily magnetized than steel. ii. sof...

Answer Details

Soft iron is preferred to steel in electromagnets because it is more readily magnetized than steel, which means it can be easily magnetized by a small amount of electric current. This property of soft iron allows electromagnets to be more responsive and efficient. On the other hand, soft iron is also more readily demagnetized than steel, which means it loses its magnetism quickly once the electric current is turned off. This property is important because it allows the electromagnet to be turned on and off quickly, which is necessary for many applications. Therefore, the correct answer is option "i and ii only". Soft iron is not preferred to steel because it retains magnetism more than steel.
