From Ampere’s circuital law for a long straight wire of circular cross-section carrying a steady current, the variation of magnetic field in the inside and outside region of the wire is:
Uniform and remains constant for both the regions
A linearly increasing function of distance up to the boundary of the wire and then linearly decreasing for the outside region
A linearly increasing function of distance up to the boundary of the wire and then decreasing one with dependence for the outside region
A linearly decreasing function of distance up to the boundary of the wire and then a linearly increasing one for the outside region
To solve this problem, we will use Ampere's circuital law to determine the magnetic field inside and outside a long straight wire of circular cross-section carrying a steady current.Ampere's circuital law states:
