Given that,
Length = 44 cm
Current = 10 A
Now, for circle
the length is bent in form of circle then the circumference is
2πr=44
r=442π
Now, the magnetic field is
BA=μ0I2πr
BA=4π×10−7×10×2π2×44×10−2
BA=0.89×10−4T
Now, for square
Length 44 cm is form in square
So, each side has length 11 cm
Now, the magnetic field due to first wire at the center
B=μ0I4πa(cos450+cos450)
Now, due to the all four wires
BB=4μ0I4πa(cos450+cos450)
BB=4×4π×10−7×10×2×24π×11×√2×10−2
BB=1.02×10−4T
Hence, the square loop will have more magnetic field at the center
