Question

The core of transformer is laminated. Why ​

Answer 1

Answer:

The core is laminated to reduce these currents to a minimum as they interfere with the efficient transfer of energy from the primary coil to secondary coil.

The core is not designed to have any currents flow through it. It is, however, a conducting loop that experiences a changing magnetic field, it will, therefore, have a small current induced in it. These are called eddy currents.

The core is laminated to reduce these currents to a minimum as they interfere with the efficient transfer of energy from the primary coil to the secondary coil.

Laminating the Iron Core :

The laminations used in a transformer construction are very thin strips of insulated metal joined together to produce a solid but laminated.
