Two long straight wires are connected by a circular section which has a radius `R`. All the three segments lie in the same plane and carry a current `I`. The magnetic induction at the centre `O` of the circular segments is

A

`(mu_0 I)/(4pi R)`

B

`(alpha mu_0 I)/(4pi R)`

C

`alpha mu_0 I)/(R )`

D

`(alpha mu_0 I)/(2pi R)`

Text Solution

Verified by Experts

The correct Answer is:
B
`B = (mu_0 I)/(R ) xx (theta)/(4 prod)`
