Introduction

  • The spatial variation of the vector and scalar physical quantities is an important aspect in study of electrodynamics. The term spatial variation has a reference to the position of the system. In most of the real-life applications, we are mainly interested in knowing how a physical quantity undergoes a variation from point to point in space at a given time instant. What is the net result of such variation on the system? Can any one of such results be used for real life application?
  • We obser…

Inter Conversion of Operator between Co-Ordinate Systems

For conversion of from one coordinate system to the other, a step-wise procedure can be developed. As an example, note the procedural steps for conversion of del operator from Cartesian to Cylindrical System.

  • Step 1: Note the expression for del in Cartesian coordinate system.
  • Step 2: Note the relations between coordinates in cylindrical and C…
