Carbonyl iron powders are basically constituted of micrometer size spheres of iron coated in a thin layer of electrical insulation.
Why iron core of transformer laminated.
The reason we laminate the iron cores in transformers is because we want to limit what are called eddy currents.
Why a transformer core is laminated.
Eddy current is induced in core and circulates normal to the width of the core causing heat.
Reduce eddy current losses.

Decrease the reluctance of the magnetic path.
Does it depend core size and material.

Provide support to windings.
The iron core transformer has higher permeability thus it is applied in transformer in place of air core in modern transformer.
The core of any transformer is laminated for the following reasons.
This is equivalent to a microscopic laminated magnetic circuit see silicon steel above hence reducing the eddy currents particularly at very high frequencies.
Iron core is thin laminated in transformer to avoid the loss of eddy current.
Why is the core of a transformer is laminated.
Hello this question is regarding one of my school projects assignments.
I would like to know why core of transformer is laminated.
Does it also depends on the size of core.
Hello this question is related to my school project assignment i would like what happens when a core of transformer is laminated.
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.
Transformers are basically two coils of wire wrapped around a core of iron.
To control it s weight regulate the energy loss due to eddy currents increase the formation secondary voltage.
