Inductance circuit symbols
The circuit symbol for an inductor indicates the coil nature of the inductor. There are several formats indicating whether the inductor or transformer has a air core or a magnetic core.
Transformer circuit symbols
While the basic inductor is widely used in many circuits, the transformer is also used in very many applications.
The advantage of ferrite and iron cores is that they significantly increase the level of inductance and also in the case of a transformer, the coupling between the input and output inductors. They do introduce losses. Air cored inductors and transformers have lower levels of inductance and are often used for RF applications where lower levels of inductance are needed.
