The iron core is there to provide a path for the magnetic flux to link both the primary and the secondary with as little flux as possible linking only one of the windings.
The cross-section area of the core determines how much magnetic flux there is, because transformer iron has a fixed maximum flux density, usually 1 Weber per square metre.
The amount of flux determines how many volts per turn there are on both windings.

What is the definition of a core in electrical equipment?
A core in the electrical trade usually refers to the iron laminations that coils of wire are wrapped around. The core directs the magnetic field, that the coils of wire produce when energized, into a working force. This could be the iron core of a relay or a transformer core that is the centre and principle reason that a transformer can operate.
Why do you need varnish in transformers?
A: The iron on a typical transformer is made up by adding iron leaves to the core. These leaves will vibrate if held loosely by a screw which add to eddy current. to stop the vibration varnish is applied to keep the leaves of iron coherent
What kind of device is a telsa coil?
Tesla coil is a resonant air core transformer. There are other known devices that are like the Tesla coil.
What is mercurys core up of?
Mercury's core is made of iron, with a diameter of 3600 km to 3800 km. The silicate outer shell is only 500 to 600 km thick. At least some of the core is molten.

Electronic prescribing is a core function of an electronic health record?
True
What is the use of core transformer?
500w iron core transformer .that kind of size
What is the function of the core?
the function of core is to provide path to magnetic flux,a core may be armature core or may be transformer core
What happen if wood is used for making transformer core instead of iron?
It would not function. In general, the core must be made of a material with certain magnetic properties. Wood has none.
What is the function of placing a laminated iron core like that of transformer at the back of the field winding in pedestal fan?
iron core is used as an electromagnetic as electric energy is converted in to magnetic energy which in turn converted in to mechanical energy
Why are stripes of iron plates joined instead of using a single block of iron core in a transformer?
To reduce heat generated and eddy current losses in transformer's core during operation.
What will happen to the efficiency of a transformer if the iron core is removed?
its efficiency will decresed.
What is mean by magnetizing current of transformer?
A: As current flow in the primary it will magnetize the core of the iron in the transformer that is called magnetizing.
How the voltage is induced in a single phase transformer?
The changing magnetic flux in the iron core of the transformer induces a voltage in the windings.
Function of no-load in transformer in a open-circuit?
To calculate the no load current from transformer & core loss is also calculated.
CAN you able to use any other thing instead of iron core in transformer?
shell type core can be used

Is the transformer's iron core called the primary?
No. the primary winding is called the primary; the secondary winding is called the secondary. These are both wrapped around the iron core of the transformer. The core helps magnetically link the primary and secondary, which causes the transformation of voltage and current from primary to secondary.
