Ampere’s law differential form 5.3 Divergence and Curl of B
I Drawing magnetic field lines: The lines are closed or go to infinity. The lines encircle the current. The lines are perpendicular to the current. Direction from the right-hand rule For current distributions, decompose into wires and use superposition.
Ampere’s law integral form Simple solutions for: Infinite straight lines Infinite planes Infinite solenoids Toroids
