Question

41. A large straight current carrying conductor is bent
in the form of L shape. Find B at P ​

Answer 1

Answer:

given = large straight current carrying conductor is bent in L shape.

to find = magnetic feild i.e. B

solution =

B = B1 +B2 ...........1 (in vector form )

B1 = μοi/4πa (cosθ1 +cos0) K .......2

B2 = μοi/4πa(cosθ1 + cos0)k......3

add the equations,

B = μοi/ 4πa(cosθ1+cosθ2+2)k

cosθ1=cosθ2 = 1/√2

so, the B= (2+√2) μοiK/4πa
