Question

Write down biot savart low in vector from

Answer 1

Answer:

Explanation:

The Biot Savart's Law we know is given by:

δB

=4πμ0​​r2Idlsin(θ)​r^, where θ is the angle between the line element dl

and the radial unit vector r^.

Now we know: r^=rr

​, using this and the cross product of two vectors we get; δB

=4πμ0​​r3I(dl

×r

)​

Answer 2

Answer:

Biot Savart law states that the magnetic field due to a tiny current element at any point is proportional to the length of the current element, the current, the sine of the angle between the current direction and the line joining the current element and the point, and inversely proportional to the square of the ...
