An infinitely long straight conductor is bent into the shape as shown in the figure. It carries a current I ampere and the radius of the circular loop is r metre. Then the magnetic induction B at the centre of the circular part is:
Options
- Azero
- Binfty
- C( _ o 2 I 4 r ( +1) )
- D( _ o 4 2 I R ( -1) )
Correct answer
D. ( _ o 4 2 I R ( -1) )
Step-by-step solution
( aligned & B= | OI 2 R - OI 2 R | & B = Oi 2 R (1- 1 11 ) & = o i 2 R ( -1) & = o 4 2 I R ( -1) aligned ) ( ) Option D is correct answer.
