When light enters your pupils, it refracts on your cornea and projects an image of your surroundings on your retina, a tiny screen in the back of your eye.

If, by 'one piece', you mean solid -as opposed to laminated- then the answer is that a solid core will have significantly-higher eddy current (circulating current) losses than a solid core.
to reduce the eddy current loss in the machine
Instead of a single piece of metal, the armature is made up of laminated thin metal plates. The thickness of the laminations is determined by the supply frequency. They are approximately 0.5mm thick. For the armature core, silicon steel laminates are used to reduce eddy currents and hysteresis losses.
the heat formed in the core due to the "eddy currents" burns a transformer
The iron core of Transformers is laminated to reduce eddy currents, which cause a loss of energy.

Primary and secondary winding and mutual induction principle.
Toroidal transformers produce less radiated noise (50 or 60 Hz hum) and generally are smaller and lighter than conventional laminated steel core transformers.
If the transformer had a solid core it would build up eddy currents within the core possibly making the core itself rise in voltage. The laminations break up these eddy current circuits and prevent this.

by using the laminated core
There is a laminated iron core for the magnetic field and then a lot of enamelled copper wire. Step-up transformers use the same materials.
iron has high permeabiliy than others and also less leakageAnswerGenerally speaking, transformer cores are manufactured from laminated sheets of silicon steel, not iron.
choke
All basic mutual transformers have a laminated silicon-steel core, around which are placed a primary winding and a secondary winding.Practical transformers can be much more complicated. They may contain multiple windings, terminal bushings, tap-changing mechanisms, oil-cooling arrangements, and protective devices.
Insulation of laminated core is required to reduce the circulating current points due to touching the two plates. This results in more iron loss and heat produced
