Answer:
Explanation:
As per Ampere's law of magnetic field we know that
line integral of magnetic field along closed ampere's loop is equal to the product of current enclosed and magnetic permeability of medium
So it is given as
here we can say that enclosed current is given as
now from ampere'e loop law for any point inside the wire we will have
now we know that magnetic field inside the wire is 84% of the field at its surface
so we will have
so we have
now we know
here i = 2 A
so now we have
