In optics it often suffices to consider the variations of a scalar variable rather than those of the field vectors, where the scalar variable may stand for any of the components of a field vector, or even for a surrogate variable simulating the variations of the field vectors. For instance,...
this energy-intensive process is achieved by applying an external magnetic field or spin-polarized currents. An emerging alternative, however, is the use of an electric field to control magnetic anisotropy, which could offer a more energy-efficient ...
The potential defined in this way is a scalar quantity, having magnitude but not a direction, whereas the electrical force is a vector. This comes about from integrating the dot product of Fint with ds where ds is the distance increment that points along the pathway taken from infinite ...
So for this problem I think I am doing something weird with the trig and/or vector components. I calculated the problem like this: First drew a picture, q1 and q2 on the x axis. q3 located equidistant between them but negative .300m in the y direction. First finding magnitude of Elect...

This paper involves the implementation of a Closed Loop Flux Observer (CLFO) on a vector controlled drive that was designed for an electric vehicle. An Indirect Rotor Field Orientation (IRFO) system can encounter problems at a high speed of operation, and these can drastically reduce its ...
What problem solving advantages do scalar and vector potential functions offer compared to dealing directly with the electric and magnetic fields? Explain the applications of magnetism in the medical field. Describe and explain the Maxwell-Faraday equation. Define equipotential surfaces. Why are equipotent...
Two such functions are the scalar potential function ϕ and the vector potential function A. The four first-order field equations can be transformed into two second-order equations in the potential functions that can be integrated. The magnetic vector B has a zero divergence and it is said ...
Most often in such cases, scalar and vector methods are used to control the asynchronous motors, driving individual wheels of the bogie through integrated gears. In the case of scalar control, the most common method is the control method maintaining a constant voltage to frequency ratio (U/f ...
