الكهرباء هي مجموعة الظواهر الفيزيائية المرتبطة بوجود وحركة المادة التي لها خاصية الشحنة الكهربائية. ترتبط الكهرباء بالمغناطيسية، وكلاهما جزء من ظاهرة الكهرومغناطيسية، كما وصفتها معادلات ماكسويل.
Electricity is the set of physical phenomena associated with the presence and motion of matter that has the property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell’s equations.
The Electrical Engineering: Sensors are critical components in all measurement and control systems. The need for sensors that generate an electronic signal closely followed the advent of the microprocessor and computers.
This book provides an overview of numerical field computational methods. Particular attention is paid to the finite element method (FEM) for the design of electrical machines and other magnetic devices.
