HWH # due ${12}^{th}$ Dec. $2024$ an inf. long, straight, solid, non$-$magnetic conductor, with a circular cross$-$section of radiur $b$ carries a stea dy current I

Determine the mag. flux density both inside and outsite of the conductor?

Cylindrical Symmetry.

Align the conductor along

axis. Then, vec$(B)$ will be

$\frac{O}{?}-$dinected and will be constant along any circular path around $z-$
