Question

Soft iron is used to make the core of transformer, because of its
low
coercivity and low retentivity
(2) low coercivity and high retentivity
(3) high coercivity and high retentivity
(4) high coercivity and low retentivity​

Answer 1

Answer:

3

Explanation:

The soft iron core increases the strength of the magnetic field inside a transformer. The main purpose of using an iron core in a transformer because iron is a magnetic material and it is easily available everywhere. The core is laminated to reduce the Eddy current and hence Eddy current losses

Answer 2

Answer:

(2) low coercivity and and high dentistry.
