Draw magnetic field lines in and around a current carrying straight solenoid.

What does the divergence of magnetic field lines near the ends of a current carrying straight solenoid indicate?

(a) Draw magnetic field lines produced around a current carrying straight conductor passing through a cardboard. Name, state and apply the rule to mark the direction of thers field lines. (b) How will the strength of the magnetic field change when the point where magnetic field is to be determined is moved away from the straight wire carrying constant current? Justify your answer?
