Answer:[tex]B=6.28\times 10^{-5} T[/tex]
Explanation:
Given
No of turns [tex]n=20 turns[/tex]
radius of Loop [tex]r=10 cm=0.1 m[/tex]
current [tex]i=0.5 A[/tex]
Magnetic Field at center of loop is given by
[tex]B=\frac{\mu _0nI}{2r}[/tex]
[tex]B=\frac{4\pi \times 10^{-7}\times 20\times 0.5}{2\times 0.1}[/tex]
[tex]B=628.4\times 10^{-7} T[/tex]
[tex]B=6.28\times 10^{-5} T[/tex]
