iron has high permeabiliy than others and also less leakage
AnswerGenerally 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 .
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.
It steps down voltage by moving the iron core spacing. Mostly using on high current welding transformer. Easy to achieve changing output voltageand does not need to use high power selector to switch voltage
500w iron core transformer .that kind of size
The inner core is made up of an iron-nickel fluid.
Soft iron core
The inner core is made up of an iron-nickel fluid.
shell type core can be used
Toroidal transformers produce less radiated noise (50 or 60 Hz hum) and generally are smaller and lighter than conventional laminated steel core transformers.
Its only multyplayer on live
Mercury.Btw use the correct wording on questions. Meaning you should have asked "Which planet has a core of iron larger than our moon?"
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.
