The operating system is the most important software on a computer. It is responsible for managing hardware and software resources and allows the computer to run applications. It starts as soon as the computer is switched on and serves as the foundation for other programs to run. Examples of operating systems include Windows, macOS, and Linux.
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.)
