Explaining how a transformer works Practical Physics

The iron core of a transformer is normally a complete ring with two coils wound on it. One is connected to a source of electrical power and is called the 'primary coil'; the other supplies the power to a load and is called the 'secondary coil'.

Iron core transformers are usually used when the source frequency is low (below 20 kHz). A soft iron core transformer is very useful where the transformer must be physically small, yet efficient. The iron core transformer provides better power transfer than does the air core transformer. A transformer whose core is

What Is the Role of Iron Core in a Transformer

The iron core in a transformer channels the magnetic flux created by the current flowing around the primary coil to link as much of it as possible to the secondary coil connected to it. Transformers can thus step up or step down the voltage of alternating electric currents.

Core of Transformer and Design of Transformer Core

Purpose of Transformer Core In an electrical power transformer, there are primary, secondary and may be tertiary windings.The performance of a transformer mainly depends upon the flux linkages between these windings. For efficient flux linking between these windings, one low reluctance magnetic path common to all windings should be provided in the transformer.

The iron core transformer provides better power transfer than does the air core transformer. A transformer whose core is constructed of laminated sheets of steel dissipates heat readily; thus it provides for the efficient transfer of power. The majority of transformers you will encounter in Navy equipment contain laminated steel cores.
