1. Answer:

   [tex]I=1.9A[/tex]

   Explanation:

   From the question we are told that:

   Meter distance [tex]d=0.0525[/tex]

   Magnetic field [tex]B=7.14*19^{-6}T[/tex]

   Generally the equation for Magnetic field B is mathematically given by

    [tex]B =\frac{\mu *I }{2* \pi r}[/tex]

    [tex]7.14*19^{-6}T =\frac{ 1.26 *10^{-6} *I }{2* 3.142*0.0525}[/tex]

   Where

   Constant[tex]\mu=1.26 *10^{-6}[/tex]

    [tex]I=1.9A[/tex]

   Therefore

   The Current through the wire is

    [tex]I=1.9A[/tex]
