  1. 1. We know that the Electro static potential Just as above we define vector magnetic potential We know that …1 …2 Substitute 1 in 2 The vector identity …3 Derivation of Boit-Savart’s Law
  2. 2. …4 …5 Substitute 5 in 4 …6 Substitute 6 in 3 …7
  3. 3. The vector identity We know that We know that Substitute eqn.4 in eqn.3 …..5 Derivation of Ampere’s Circuital Law …1 …2 Substitute eqn.2 in eqn.1 …3 …..4 We know that We know that …..6 Substitute eqn.6 in eqn.5 …..7 Substitute eqn.8 in eqn.7 …..8
  4. 4. By using stokes theorem We know that Substitute eqn.2 in eqn.1 …1 …2 We know that …3 .…4 Substitute eqn.4 in eqn.3 .…5 The vector identity We know that …6 …7 Substitute eqn.7 in eqn.6 …8 We know that Substitute eqn.9 in eqn.8 …..10 …..9 We know that …..11
  5. 5. We know that Substitute eqn.11 in eqn.10 …..12 Substitute eqn.13 in eqn.12 …..13 …..14
  6. 6. Let us now consider the force between two elements and According to Biot-Savart's law, both current elements produce magnetic fields. So the force on element due to the field produced by element The total force on current loop 1 de to current loop 2
