A straight wire carrying a current of 12 A is bent into a semi-circular are of radius of` 2.0` cm as shown in the adjoining figure (a). Consider the magnetic field B at the centre of the arc. Would your answer be different if the wire were bent into a semi-circular arc of the same radius but in the opposite way a shown in figure (b)?

A thick straight copper wire, carrying a current of 10 A is bent into a semicircular arc of radius 7.0 cm as a shown in Fig (a). (i) State the direction and calculate the magnitude of magnetic field at the centre of arc. (ii) How would your answer change if the same wire were bent into a semicircular arc of the same radius but in opposite way as shown in Fig. (b)?
