Magnetic Properties of Materials: Magnetic Properties of Materials - From the magnetic point of view a material is classified according to the nature of its relative permeability (μr). All nonmagnetic…
Magnetic Circuits and Induction Articles: Magnetic Field Equation: The exact description of the Magnetic Field Equation Basics is given by the Maxwell’s equations and the constitutive relationship of the medium…
Magnetic Circuit Analysis: Magnetic Circuit Analysis - The presence of charges in space or in a medium creates an electric field, similarly the flow of current in a conductor sets…
Reflection of Electromagnetic Waves by a Conducting Surface: In view of the way in which signals propagate in waveguides, it is now necessary to consider what happens to Reflection of…
Electromagnetic Spectrum: In an earth environment, electromagnetic waves propagate in ways that depend not only on their own properties but also on those of the environment itself; some of this…
Fundamentals of Electromagnetic Waves: Fundamentals of Electromagnetic Waves are energy propagated through free space at the velocity of light, which is approximately 300 meters per microsecond. As the object travelled downward,…
Magnetic Circuit Calculations: Normally magnetic circuit calculations involve two types of problems. In the first type of problem it is required to determine the excitation (mmf) needed to establish a…
BH Curve Relationship (Magnetization Characteristic) for Ferromagnetic Material: In free space (also nonmagnetic materials), the permeability μ0 is constant so that BH Curve Relationship is linear. This, however, is not the…
