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.

Text Solution

Verified by Experts

The correct Answer is:
`[(mu_(0)I)/(h) sqrt(1 - ((h)/(2pi T))^(2)), (mu_(0)I)/(2pi r)]`
