The figure shows a current-carrying loop, some part of which is circular and some part is a line segment. The magnetic induction at the centre is

Answer:

Solution:

The magnetic field due to circular arc is

$B = \frac{μ_{0} I α}{4 π r} = \frac{μ_{0} I}{4 π a} (\frac{3 π}{2}) = \frac{3 μ_{0} I}{8 a}$
