The reason we laminate the iron cores in Transformers is because we want to limit what are called eddy currents. Transformers are basically two coils of wire wrapped around a core of iron. They work by induction. Induction occurs when current flows in one conductor (or one set of windings in the transformer) and the magnetic field that forms around that conductor (that set of windings) sweeps the other conductor (the other set of windings) and induces a voltage. In order to increase the effectiveness of the transformer, we need to improve the way the magnetic fields are coupled from one set of windings to the other set. Iron conducts magnetic lines of force well, so we use that to help conduct the magnetic lines of force from coil A to coil B. Problem is, iron is also a conductor, and it's being swept by the magnetic field as well. If we didn't use laminations, the iron core would provide a place for the magnetic lines to produce (induce) current, and that current flowing in the core would heat the core up really fast and waste energy. By laminating the cores, we break up the current paths within that core and limit eddy currents.
No, the purpose of laminating the core is to reduceeddy-current losses.

The iron core of transformers is laminated to reduce eddy currents, which cause a loss of energy.
Some energy is lost in most machines, in most energy transformations. In the case of transformers, the main problem is eddy currents - unwanted currents, that are minimized, but not eliminated completely, by laminating the iron.
Low hysterisis loss and high permeability
besides 10 numerical difference there is the transformers iron core of to be considered it will take more iron for the same current to keep it from saturating.
iron has high permeabiliy than others and also less leakageAnswerGenerally speaking, transformer cores are manufactured from laminated sheets of silicon steel, not iron.
It is because if we use a plastic as a core of the transformer then induced emf can to be produced also generated heat will damage the plastic .
1. provide a frame to fix the primary and secondary coil in place. 2.allow magnetic flux to flow across. 3.acts as temporary ferromagnet which amplifies magnitude of flux.
what is iron core inductors
The purpose is to enhance the magnetic field - to make it stronger - compared to just using air.
