Always wear PPE when working in environments with potential health or safety risks.
PPE stands for Personal Protective Equipment, which includes gear like gloves, helmets, and goggles to ensure safety during hazardous activities.
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.)
