Answer 1

Answer:

Magnetic Effect of current is first introduced by Biot Savart

Explanation:

As per Biot Savart law the magnetic field induced due to current carrying small element is given as

$dB = \frac{\mu_o i dL sin\theta}{4\pi r^2}$

also in vector form we can say

$\vec {dB} = \frac{\mu_0 i \vec {dL} \times \hat r}{4\pi r^2}$

so here we know

idL = small current element with length dL and current i

[tex]\theta[tex] = angle between small current element and position of the point where field is to be determined

r = distance of the point from current element
