Question

State and explain Boit-Savart’s Law.

Answer 1

$biot - savarts \: law \: (laplace \: law)$

The magnitude of magnetic induction at a

point due to a small element of current

carrying conductor is directly proportional to

the current, directly proportional to the length

of the elements, directly proportional to the

sine of the angle between the elements and

the line joining the center of the element to the

point and inversely proportional to the square

Of the distance of the point from the center of

element.

We have,


$db \: \alpha \\ i \: and \: dl \: and \: \sin(o)$


$db \: inversly \: proportional \: to \: {r}^{2}$


$d \beta \: \alpha \: idl \sin(o) \div {r}^{2}$


$d \beta \: = kidl \sin(o) \div {r}^{2}$


Where K is the constant.





I hope you understand.
