A thin conducting strip of width his tightly wound in the shape of a very long cylindrical coil with cross-sectional radius R to make a single layer straight solenoid as shown in figure-4.81. A direct current `I` flows through the strip. Find the magnetic induction inside and outside the solenoid as a function of the distance r from its axis.
