Lecture 31 Inductor Types And Associated Magnetic Cores

2 2 lecture 31 inductor types and associated cores a magnetic core choices inductors are made by winding copper wire around magnetic cores the cores usually contain an air gap purposefully cut into them to improve energy storage since the role of an inductor is to store energy we will usually have one or more air gaps in the magnetic flux path of the core employed for an inductor.
