Copper Foil
The copper coil is the most commonly used material for electric transformers. The coil winding wire is usually made up of a large number of turns of copper wire wound around a core made of magnetic material such as iron.
The purpose of the core is to concentrate the magnetic field, which enhances the efficiency of the transformer.

Feature
Firstly, copper has an excellent electrical conductivity of around 58 million siemens per meter. This high conductivity allows the current to flow efficiently through the coil, which reduces energy loss in the form of heat.
Secondly, copper is highly ductile, which means it can be drawn into thin wires without breaking. This property is critical in transformer design because the wire must be thin enough to provide a large number of turns without breaking.
Lastly, copper is highly malleable, which means it can be easily formed into any shape, making it easy to manufacture the coils.
