A ”template” is a cut-out design pattern used to replicate an identical shape on another surface. It is commonly used in various crafts, including embroidery, where it guides the placement of stitches or patterns on fabric. Templates ensure that the design remains consistent and accurate when reproduced on different materials or surfaces. They are an essential tool for precision in design work.
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.)
