Why is the core of a transformer laminated.
Why transformer cores are laminated.
Eddy current is induced in core and circulates normal to the width of the core causing heat.
In transformer the eddy current loss is proportional to the square of the diameter of the core larger the diameter more the eddy current loss.
Why iron core is thin laminated in transformer.
Hence transformer core is laminated so that the net effective diameter of the transformer core reduces and thus eddy current loss can be minimized.
To control it s weight regulate the energy loss due to eddy currents increase the formation secondary voltage.
The purpose of providing an iron core in a transformer is to.
A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical electromechanical and magnetic devices such as electromagnets transformers electric motors generators inductors magnetic recording heads and magnetic assemblies it is made of ferromagnetic metal such as iron or ferrimagnetic compounds such as ferrites.
These are called eddy currents.
Comment related questions on transformers.
The core is not designed to have any currents flow through it.
The iron core transformer has higher permeability thus it is applied in transformer in place of air core in modern transformer.
But a solid iron core has some own disadvantage due to to some losses.

For this reason electrically isolated laminations are utilized to manufacture transformers.
A transformer core is laminated to.
Does it depend core size and material.
Laminated magnetic core reduces eddy currents.
Why a transformer core is laminated.
Reduce all above losses.
It is however a conducting loop that experiences a changing magnetic field it will therefore have small current induced in it.
The core of any transformer is laminated for the following reasons.
Reduce eddy current losses.
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.
