What Is a Transformer Core?
A transformer core, also known as the iron core of a transformer, refers to the central component of the transformer.
Transformers are devices used to convert voltage to the required level when utilizing electricity. The iron core is situated at the heart of the transformer, with coils wound around it.
The iron core plays a crucial role in facilitating the passage of magnetic flux. When an electric current flows through the coil, it generates magnetic flux, inducing voltage in the coil by traveling through the iron core. Typically, iron is used for the core, although other materials may be employed.
For instance, using a magnetic substance called ferrite allows for the creation of an effective core for high-frequency currents. Transformer cores come in various shapes such as “E-shaped,” “I-shaped,” and “U-shaped,” with the performance of the transformer varying based on its shape.
