Question

the core of the transformer is liminated. Why ?​

Answer 1

Answer:

The core is laminated to reduce these to a minimum as they interfere with the efficient transfer of energy from the primary coil to the secondary one. The eddy currents cause energy to be lost from the transformer as they heat up the core - meaning that electrical energy is being wasted as unwanted heat energy.

Explanation:

Answer 2

Answer:

Due to power losses in Eddy currents inside a continuous metal or iron core around which the coils are wrapped, we prefer to use cut short laminated sheets, so that tiny circuits are not formed due to dis continuation of matter for the creation of loops.
