Step 1

Consider a small segment dx of circular path on the surface of cylindrical.

Calculate the differential current flowing in the in the small segment,

Step 2

Consider this segment of circular path as a ring and calculate the magnetic field at the origin.

Step 3

Integrate the above expression for z = 0 to z = 5 to calculate the total magnetic f...
