Many wonder what is the function of iron core transformer. The iron core in a transformer facilitates max flow of magnetic flux between primary and secondary windings. It result in inducement of the same voltage in both windings is possible.
You use an iron core in a transformer because you want to maximize the efficiency of the transformer. Transformers work on the principle of magnetic coupling between two or more alternating current carrying windings. You need a ferrous material to focus the magnetic lines of force, and iron is particularly good as a ferrous material.
Another Answer
Iron is a 'soft' magnetic material, which means that it can be magnetised and demagnetised very easily. When we pass an alternating current through the primary winding of a transformer, an alternating magnetic field is set up within the core. Iron allows this magnetic field to increase, decrease, and reverse, as the current varies, very easily and without any significant loss of energy. Steel, on the other hand, is a 'hard' magnetic material, which means that it is difficult to magnetise and demagnetise, and requires a great deal of energy, making it unsuitable for a transformer core.
Incidentally, transformer cores are often described as being manufactured from 'silicon steel' or 'transformer steel'. These are misnomers, because they are actually manufactured from silicon iron.
To 'contain' the magnetic flux produced by the primary winding, to ensure that it links with the secondary winding with the minimum 'leakage'. The core is a magnetic circuit manufactured from laminations of silicon steel, to maximise the flux density and to minimise eddy-current and hysteresis losses.
hysteresis loop has minimum loop area...so core loss willl be minimum....
You will have a very expensive but worthless transformer. Gold is not a ferromagnetic material, so it will not contain the magnetic flux needed to link the separate windings.
Because aluminium is, in simple terms, 'non-magnetic' and will not support the formation of magnetic flux. 'Soft' ferrousmetals with low reluctance* (i.e. metals such as iron or silicon steel) must be used.[*'reluctance' is equivalent to 'resistance' in an electric circuit]
i think Transformer operates AC and ferrite core operates in DC
The container the transformer core and windings are placed inside is the tank.
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
The transformer core is ferromagnetic in order to focus and concentrate the magnetic fields generated in the windings. This improves coupling and increases inductance.
No. Transformers operate on the principle of conversion of electric current to and from magnetism. Optic fiber is not ferromagnetic, nor is it conductive.
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
500w iron core transformer .that kind of size
It is the current transformer core meant for metering.

Loadestone
non linear B-H characteristics
Its called an electromagnet
shell type core can be used

A 'core type' transformer core is one in which the primary windings and secondary windings are placed around each of the limbs, as opposed to a 'shell type' core, in which the two windings are placed across the centre core. A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit. This is better answered with a diagram, so I suggest that you do a search on the internet.
