    Answer:

    I=1.9A

    Explanation:

    From the question we are told that:

    Meter distance d=0.0525

    Magnetic field B=7.14*19^{-6}T

    Generally the equation for Magnetic field B is mathematically given by

     B =\frac{\mu *I }{2* \pi r}

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

    Where

    Constant\mu=1.26 *10^{-6}

     I=1.9A

    Therefore

    The Current through the wire is

     I=1.9A
