A wire is bent in the form of a circular arc with a straight portion AB. Magnetic induction at O when current flowing in the wire, is

A long current carrying wire is bent as shown. The magnetic field induction at O is

Two identical wires each of length L are bent to form a circular loop and a square loop. If the same current i flows in the two wires, then the ratio of the magnetic inductions at the centre of the circular and square loops is :

A portion of a conductive wire is bent in the form of a semicircle of radius r as shown below in fig. at centre of semicircle, the magnetic induction will be

Figure. Shows a small loop carrying a current I. The curved portion is an arc of a circle of radius R and the straight portion is a chord to the same circle subtending an angle theta . The magnetic induction at centor O is
