Magnetics cores can be divided into many types of categories.  This discussion will divide magnetic cores into two major categories, structure (shape) and material.  These major core categories will then be sub-divided into additional categories.

Further below are a list of core structures and a list of magnetically "soft" core materials.  The lists are not intended to be exhaustive lists.  The associated discussions are intended to be general information, not detailed information.  Butler Winding uses magnetic cores in its production of transformers and inductors, but does not manufacture any cores other than stacking laminations to form core stacks.  Some additional information can be obtained from other web pages within Butler Winding’s website.  Also feel free to contact Butler Winding and ask to talk to our engineering personnel.  You can also contact core manufacturers for more detailed core information.
