## derive an expression for magnetic field due to a straight current carrying conductor [finitely and infinitely long]

We know that when electric current flows through the straight current-carrying conductor then it creates a magnetic field that encircles the conductor as shown below: Learn more about magnetic field due to straight current-carrying conductor.  So it is okay that…
