Key characteristics of democracy include free and fair elections, equality before law, and the dignity of individuals. While majority rule is a democratic principle, it must respect minority rights and cannot override equality or dignity.
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.)
