Question

Small current element id with d l is equals to 2 km m and a is equals to it is centre at the origin find the magnetic field db at the given points first on the axis at x is equals to cement

Answer 1

IDK THE ANSWER PLS EXPLAIN

Answer 2

Answer:

i) 4.44 × 10 ^ -11 j Tesla

ii ) 0.11×10^−7 j Tesla

iii ) zero

Explanation:

According to the biosevert law magnetic field due to small element is given by:

db =μ0I4πr3dl×r

where θ is the angle between length vector andr vecter.

I=2A

dl=2k

1)x=3

r=3i

db=μ0I4π33(2k×3i)=4π33μ0I6j=0.44×10−7 T in positive y direction.

(2) x=−6m

r=6m

r=−6i

db =μ0I4π63(2k×−6i)=4π63μ0I12(−j) =0.11×10−7 T in negative y direction

(3) z=3m

r=3m

r=3k

db=μ0I4π33(2k×3k)=o

hope so it's help u :)
