Magnetic Field from Non-Uniform Current

Mark

A cylindrical conductor of radius $R$ carries a current with a non-uniform density given by $J = kr$ , where $k$ is a constant and $r$ is the radial distance from the central axis. What is the magnitude of the magnetic field at a distance $r < R$ from the axis?

$\frac{\mu_0 I}{2 \pi r}$

$\frac{\mu_0 k r^2}{3}$

$\frac{\mu_0 k r^3}{4}$

$\frac{\mu_0 k r^3}{3}$
