Explanation:
From the question we are told that
The inner radius is
The outer radius is
The nu umber of turns is
The current it is carrying is
Generally the magnetic field is mathematically represented as
Where is the permeability of free space with a constant value
And the given distance where the magnetic field is felt is r = 0.9 cm = 0.009 m
Now substituting values
Fro the second question the distance of the position considered from the center is r = 1.2 cm = 0.012 m
So the magnetic field is
