Electromagnectic Fields, 2nd Edition[Softcrate]

The discipline of electromagnetic field theory and its pertinent technologies is also known as electromagnetics. It has been based on Maxwell’s equations, which are the result of the seminal work of James Clerk Maxwell completed in 1865, after his presentation to the British Royal Society in 1864. It has been over 150 years ago now, and this is a long time compared to the leaps and bounds progress we have made in technological advancements. But despite, research in electromagnetics has continued unabated despite its age. The reason is that electromagnetics is extremely useful, and has impacted a large sector of modern technologies. From a classical perspective in the history of electromagnetism, the electromagnetic field can be regarded as a smooth, continuous field, propagated in a wavelike manner; whereas from the perspective of quantum field theory, the field is seen as quantized, being composed of individual particles. EM theory is an essential basis for understanding the devices, methods, and systems used for electrical energy. Both electric and magnetic fields are defined in terms of the forces they produce.
