To control it s weight regulate the energy loss due to eddy currents increase the formation secondary voltage.
Why is the core laminated.
The core of the transformers needs to be laminated to reduce the eddy current that has arisen from the induced voltages through the core reducing the heat loss of the whole core which is why the core of the transformers is laminated to restrict the eddy currents flowing through it.
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.
Thus to reduce the losses solid core is not used in transformer.
But a solid iron core has some own disadvantage due to to some losses.
The core of any transformer is laminated for the following reasons.
Why iron core is thin laminated in transformer.
Comment related questions on transformers.
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.
The core is not designed to have any currents flow through it.
A transformer core is laminated to.
The iron core transformer has higher permeability thus it is applied in transformer in place of air core in modern transformer.
It is however a conducting loop that experiences a changing magnetic field it will therefore have small currents induced in it these are called eddy currents.
