**Core set** - a set of all designed parts forming a fully functional [[magnetic core]].[(Ferroxcube>Ferroxcube, Soft Ferrites and Accessories, Data Handbook, 2013)]

The term **//core set//** is especially applicable to soft [[ferrite core|ferrite cores]], some of which comprise several parts, usually two or three, but in special cases there can be more. 

Single-part (like toroids) do not require additional parts to form the complete set. Many core types (like [[ETD]]) are designed to be made from two identical halves. However, in the case of a [[gapped core]] it is possible to form a core set from one [[ungapped core|ungapped]] and one gapped half - because the gap is present only in the central cylindrical part. 

Some core types (e.g. [[FRM20]]) are designed such that exactly defined two parts must be used.

In some cases the parts can be used in alternative ways to form a fully functional core sets. For instance, the [[EI]] cores can be composed either as E+I or E+E. 

Three and more components can be used in core sets like [[RM]] or [[pot core|pot cores]]. The main magnetic path is created by joining the two large core halves, and the central aperture is designed to accept and additional "[[adjuster]]" which can be used for fine tuning the required level of inductance.[(Ferroxcube)]
