A ferromagnetic core, called E-, I-, U-, L-, toroidal, pot, or planar cores, depending on their shape Primary and secondary coils, also known as windings. Most of the time, the electric circuit is wound around the center leg, whose section area is twice that of each individual outer leg. The magnetic flux flows through two closed magnetic paths which decrease the core losses and hence increase the efficiency of transformer.So, shell type transformer gives more output compared to similar core type transformer.

There are two main types of transformers which can be categorized by the shape of the magnetic core. So we can now determine the number of turns in the primary. Now, we take all these constraints, and we can design the rest of the transformer.

If an air gap is required, the centre leg of the "E" is shortened so that the air gap sits in the middle of the coil to minimise fringing and reduce electromagnetic interference. You should consult with a core manufacturer to obtain the specific characteristics and power-handling capabilities for each type and. That means, the core Kg must be larger than the design Kg.
