two wire A and B of same lenght is equal to 44cm and carrying a cxurrent of 10A each. wire A is bend intop a circle and wire B into square. which wire will produce greter magnetic field at the centre?

At centre of square there is a greater magnetic field.. ...because in case of square   centre  is at less distance from the currentelement than that case of circle

distance between current element and centre 

    in case of square is 5.5cm



where as   in case of circle  it is 7cm
