Magnetic Phenomena, of the magnetic field of an electric current in 1820. In this chapter we shall briefly describe the principal kinds of magnetic ordering to be found in solids and shall then go on to consider in more detail the phenomena that are most relevant to electrical engineering

ICLE

Book 1990, though that epoch-making event was the result of far-sighted research planning by Bell Laboratories dating from a decade or more before: no mere chance discovery, therefore, but the fruition of work which allotted at its inception a vital role to materials. The transistor is now very old hat, but

Jocelyn Jones,Hannah McGlade,Sophie Davisoniour is that it . explain the relative magnitudes of the resistivities of materials and at least the sign of the temperature coefficient of resistivity (TCR), defined by . where ρ. is the resistivity at a reference temperature, usually 0°C, α is the TCR and ρ is the resistivity at Δ. degrees above (
