what is net magnetic field at point O? Share with your friends Share 10 Vijay Shankar Yadav answered this Dear Student, we know magnetic field at the center of (curvature subtending angle θ)=μi4πrθso magnetic field due to inner semicircle at O=μi4r⊗and magnetic field due to outer semicircle at O=μi8r⊙so net field at O=(μi4r-μi8r)⊗=μi8r⊗ Regard 61 View Full Answer Shuktiz answered this zero -35
