Bearing: A bearing is the horizontal angle between a fixed reference direction (usually North) and a specific target or point. Bearings are used for navigation and map reading.
Types of Bearing:
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.)
