SELECTION OF ELECTRICAL STEELS FOR Magnetic Cores
www.brown.eduMagnetic cores for the wide range of modern electrical and electronic devices require magnetic materials with many combinations of properties and characteristics. Of all the soft magnetic core materials, the most widely used are known as “electrical steels.” AK Steel, as a major producer, offers a wide variety of electrical steels.
Coupled Inductors
www.maplesoft.comFigure 1: Two coils are magnetically coupled, wound around a magnetic core. With coupled inductors, such as those shown in figure 1, two wires are wrapped around a magnetic core. In this diagram, note that the two wires are wrapped around the core in opposite directions and produce the same polarity of voltage. This is due to Lenz's law. A
