Question

explain the relationship between magnetic field and the current through a conductor

Answer 1

Dear Student ,
the relationship between a current carrying conductor and magnetic field produced by it is,
$\overrightarrow{B}=\frac{{\mu }_0}{4\pi }\sum _{}^{}\frac{I\left(d\overrightarrow{l}\times \hat{r}\right)}{r^2}$
So the magnetic field is directly proportional to the current (I) flowing through the conductor .
