7.1 INTRODUCTION

Electrostatic fields are denoted by (x, y, z). Magnetostatic fields are represented by (x, y, z). If electric and magnetic fields vary with time, then these fields are called “time-varying fields”. In static electromagnetic (EM) fields, electric and magnetic fields are independent of one another. In dynamic EM fields, the two fields are interdependent. A time-varying electric field always involves a corresponding time-varying field. Time-varying EM fields are represented as (x, y, z, t) and (x, y, z, t). Time-varying ...
