Electrical Steels Volume 1: Fundamentals and basic concepts

Volume 1 covers the fundamentals and basic concepts of electrical steels. Topics covered include: • Soft magnetic materials; basic magnetic concepts; magnetic domains, energy minimisation and magnetostriction and methods of observing magnetic domains in electrical steels. • Electromagnetic induction; fundamentals of a.c. signals; losses and eddy currents in soft magnetic materials and rotational magnetisation and losses. • Anistropy of iron and its alloys; magnetic circuits; the effect of mechanical stress on loss, permeability and magnetostriction and magnetic measurements on electrical steels. • Background to modern electrical steels; production of electrical steels; amorphous and nano-crystalline soft magnetic materials; nickel-iron, cobalt-iron and aluminium-iron alloys; consolidated iron powder and ferrite cores; and temperature and irradiation dependence of magnetic and mechanical properties of soft magnetic materials
