Question

Why is iron used in transformers?

Answer 1

Transformers:

1. The transformer is essentially a voltage control device that is widely used in alternating current power distribution and transmission.

Explanation:

1. The central iron core of most transformers is made of a highly permeable material, which is typically thin silicon steel laminations.
2. These thin laminations are joined together to provide the necessary magnetic path while minimizing magnetic losses.

Thus, iron is used in transformers to provide the necessary magnetic path and to minimise magnetic losses.
