# The magnetic field is linear in the source Idl just as the electrostatic field is linear in its source ie. electric charge. Explain

From BIOT-SAVART LAW magnetic field due to source idl is given by
$d\stackrel{\to }{B}=\frac{{\mu }_{0}}{4\pi }\frac{i\stackrel{\to }{dl}×\stackrel{\to }{r}}{{r}^{3}}$
which linearly dependent on source of magnetic field idl

​Electric field due to a point charge is given by
$E=\frac{1}{4\pi {\epsilon }_{0}}\frac{Q}{{r}^{2}}$
which linearly depend on the source of filed Q
