Question

A single piece of iron is not used in transformer .why?

Answer 1

Answer:

Explanation:

Current flowing through it is more and produces more heating effect.

Also, to avoid eddy current, laminated iron core is used

Answer 2

The current flowing through the resistance of the metal heats it by Joule heating, causing significant power losses. Therefore, solid iron cores are not used in transformers or inductors, they are replaced by laminated or powdered iron cores, or nonconductive cores like ferrite.
