A wire of fixed length is bent in the shape of a circle of single turn If a current flows in the circular loop then the magnetic field at the centre of the loop was found to be equal to B Now the number of turns in the loop are increased to 3 and the current is reduced by a factor of 3 The magnetic field produced at the centre of the loop will be B 3 B14 9 B
