Abstract :
A review of the properties, applications, and engineering significance of ferrites below microwave frequencies is presented. The survey includes a discussion of the nature of ferrites, their magnetic and electrical properties, the use of the ¿Q product as a design index of efficiency, core losses, and the effects of air gaps. This is followed by a discussion of the use of ferrites in a wide variety of applications. A Bibliography is also included.
