Magnitude Optimum: The design of a controller based on the principle Magnitude Optimum that it allows all the freÂquencies to pass through in a similar way for a simple system is shown in Fig. 6.31. The…
Magnetization Characteristics of DC Generator: The emf and torque equations, and power balance has been considered so far. The consideration of the Magnetization Characteristics in this section will set the stage for determining the performance…
Magnetically Induced Emf and Force: Magnetically Induced Emf and Force - Faraday's law of induction, which is the integral form of the fourth Maxwell's equation, is given as The integrated form of Eq.(2.15) for a…
Magnetic Type Potential Transformer: Magnetic Type Potential Transformer are the oldest devices for a.c, measurements. They are simple in construction and can be designed for any voltage. For very high voltages, cascading of the transformers…
Magnetic Tape Recorder Working Principle: The major advantage of using a Magnetic Tape Recorder Working Principle is that once the data is recorded, it can be replayed an almost indefinite number of times. The recording…
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 materials are classified as paramagnetic…
Magnetic Modulator: The most reliable substitutes for electromechanical choppers are magnetic modulators. These devices reach a null stability as low as 10 μV, but their response time is often less than 2 Hz and the…
Magnetic Leakage and Fringing: Magnetic Leakage and Fringing - Figure 10.28 shows a magnetized iron ring with a narrow air gap, and the flux which crosses the gap can be regarded as useful flux. Some…
Magnetic Flow Meters: Magnetic Flow Meters are the first type of flowmeters to be considered for high corrosive applications and for applications involving measurement of erosive slurries. These meters work on the principle of Faraday's…
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 in which the field is established. Such description apart from…
