Introduction to Inductors
You can get a greater magnetic field using a core than without one. 1. AIR CORE INDUCTORS: Like the name suggests, this kind of inductor has no core – the core material is air! Since air has a relatively low permeability, the inductance of air core inductors is quite low – rarely above 5uH.
