Dr. C. I. Obinwa*


This course presents a clearer view on the understanding of Electromagnetic Fields and waves, for the development of field-related appliances, such as GSM, etc. For proper understanding, it is to be noted that most of the laws and their derived mathematical expressions (equations) are highly interwoven and inter-related that their easy understanding pose some problems. To solve these problems, clearer knowledge of vectors is necessary as Electromagnetic Fields and Waves are examples of Vector Fields. Laws and their appropriate equations and their inter-relations are explained. Some examples are; , is equivalent to F= iLB, Faraday’s law of , is also Blv. That, extension of Ampere’s law, is, the Maxwell equation which is + i) and Ampere’s law is I.
