A magnetic core is the core of an electromagnet or inductor. The properties of an electromagnet or inductor will be influenced by the core with the most important factors being:

Commonly used magnetic core structures

Straight cylindrical rod

Most commonly made of the ferrite or similar material, and used in radios especially for tuning an inductor. The rod sits in the middle of the coil and small adjustments of the rod position will fine tune the inductance. Often the rod is threaded to allow adjustment with a screwdriver. In radio circuits, a dob of wax or resin is used once the inductor has been tuned to prevent the core from moving.

The presence of the high permeability core increases the inductance but the field must still spread into the air at the ends of the rod. Laminating supplies - Supplies for your laminator: laminating pouches, roll
laminating film and laminating accessories - Factory Express has guaranteed low. The path through the air ensures that the inductor remains linear. In this type of inductor radiation occurs at the end of the rod and electromagnetic interference may be a problem in some circumstances.

Single "I" core

Like a cylindrical rod but square, rarely used on its own.

"C" or "U" core

U and C-shaped cores are the simplest solution to form a closed magnetic circuit, when used alongside a I or another C or U' core.
