The reason we laminate the iron cores in transformers is because we want to limit what are called eddy currents.
Why are iron cores in transformers laminated.
Iron has high permeabiliy than others and also less leakageanswergenerally speaking transformer cores are manufactured from laminated sheets of silicon steel not iron.
Why iron core is thin laminated in transformer the iron core transformer has higher permeability thus it is applied in transformer in place of air core in modern transformer.
Transformers are basically two coils of wire wrapped around a core of iron.
High frequency transformers and chokes can be supplied using ferrite materials in the form of rm cores pot cores ring cores and e cores as well as cores in the ep efd and etd ranges.
The iron core of a transformer is made of laminated silicon steel with special insulated coating to limit eddy current loss.
By inserting a solid iron core into the transformer when it is subjected to an alternating magnetic field parasitic currents run inside it eddy currents that heat it up.
Powder permalloy or hf iron cores are used in high specification inductor applications and for rfi suppression chokes and smpu chokes lf iron cores are normally utilized.
In reality the same situation occurs as if we wrapped a large loop around the transformer core and short circuited the two ends together.

Iron core is thin laminated in transformer to avoid the loss of eddy current.

Transmission of power and house wiring.
The core of any transformer is laminated for the following reasons.
Eddy current is induced in core and circulates normal to the width of the core causing heat.
Electrical steel also called lamination steel is specialty steel tailored to produce certain magnetic properties such as a small hysteresis area small energy dissipation per cycle or low core loss and high permeability.
To control it s weight regulate the energy loss due to eddy currents increase the formation secondary voltage.
How do you reduce eddy.
