Am I correct in the answer? The question is that: In a square of
side 0 4m,carrying a current 10 ampere, we need to find the
magnetic field at the centre

Dear Student
Magnetic field due to straight conductor=μ04π2Irwhere r is the perpendicular distance between thepoint and the straight conductorthe diagonal=2×0
4mhalf of diagonal=0 42mthe distance,r=0
42×cos450=0 2mMagnetic field=10-7×2×100
2=10-5TAnd due to all four conductors=4×10-5TREGARDS
