A coil carrying a heavy current and having large number of turns mounted in a N-S vertical plane and current flow in clockwise direction. A small magnetic needle at its center will have its north pole in

A current is set up in a wire loop consisting of a semicircle of radius 4.00 cm a smaller concentric semicircle AB and CD are long straight conductor and two radial straight lengths carrying a current I. The magnetic field at the midpoint of BC is distance d apart
