Urgent. Please help answer fast with proper step. Thank you for understanding!!!



A long wire carries a constant current I and is configured as shown on the attached figure. The circular loop has a radius R. Determine the magnetic field at the center of the loop from first principles (this means you cannot use previously determined forms).\fWe know , 0 R T The magnetic field at 0 X due to current carrying Magnetic field at Conductor - B= MOI (out of) centre O due to plane circular boop is: The direction of magnetic . Bo = MoI Coat of 2R fields are derived from Right plane ) Hand Thumb Ruled In our diagram, 0 O As both magnetic fields are out of plane, So they add up, as BTotal= Bit B2 = . Mot + hoI 2R 2 0R. 2R ( 1+ +2 ) ( Ans )
