In the following figure a current loop is shown which is made from two circular arcs of radii a and b (a lt b) , connected by radial wires. Calculate the magnetic field at the centre O.

What will be the magnetic field at the centre C o the circular loop?

A part of a long wire carrying a current i is bent into a circle of radius r as shown in figure. The net magnetic field at the centre O of the circular loop is :
