Maxwell’s Equations and their derivations

Let us first discuss the Maxwell equations. In this, let us first derive and discuss Maxwell fourth equation:

1. Maxwell’s Fourth Equation or Modified Ampere’s Circuital Law

Here the first question arises , why there was need to modify Ampere’s circuital Law?

To give answer to this question, let us first discuss Ampere’s law(without modification)

Statement of Ampere’s circuital law (without modification). It states that the line integral of the magnetic  field H around any closed path or circuit is equal to the current enclosed by the path. Continue reading “Maxwell’s Equations and their derivations”
