Why Wooden Core is not Used in Transformer

The basic working principle of Transformer is the Electromagnetic induction. The transformer consists of two windings – Primary winding and secondary winding. The winding to which supply is given is called primary winding and the winding to which load is connected is called secondary winding. When the a.c. supply is connected to the primary winding, a current flows through it and alternating flux is produced in the core. The is alternating and links with the secondary winding and induces an emf in the secondary winding according to Faraday’s Law of electromagnetic induction.

In the transformer flux from primary winding is transferred to the secondary winding thus material used for core should be able carry flux easily i.e. the core material of transformer should magnetic material with high permeability. Generally, we used silicon steel laminations because they have high permeability. If we use wooden piece in place of magnetic materials, then Transformer will not work at all because wooden core cannot provide path to the flux so flux will not link either in secondary side or primary side. In short Transformer will not work. That is why we don’t use wooden core in a transformer
