Question

State biot savarts law

Answer 1

the biot savarts law refers relates magnetic field to the current which are their sources..
finding the magnetic field resulting from a cureent distribution involves the vector product.,and is inherently a calculus problem when distance from the current to the field point is continuously changing. .

Answer 2

$\textbf{Hey there}$:

$\textbf{ Answer}$:

It states that magnetic field due to a small conductor of length (dl), carrying a current (I) at a point at distance (r), is given by:

dB = $\frac{μ_{0}}{4π}$ . $\frac{Idlsin}{r^{2}}$.ϴ

Where ϴ is the angle between the direction of flow of current and line joining the small conductor to the observation point.
