Ground search and rescue services are becoming more crucial in urban and sub-urban areas due to the increasing number of accidents, emergencies, and disasters that affect both urban dwellers and travelers. This includes incidents like natural disasters, fires, accidents, or individuals who may go missing due to medical conditions or other reasons. With dense populations and complex infrastructures in these areas, rescuers must often rely on ground-based operations to locate and assist affected individuals.
Draw the pattern of the magnetic field lines for the two parallel straight conductors carrying current of same magnitude 'I' in opposite directions as shown. Show the direction of magnetic field at a point O which is equidistant from the two conductors. (Consider that the conductors are inserted normal to the plane of a rectangular cardboard.)
