    Answer:

    The magnetic field inside the cylindrical resistor is \dfrac{\mu_{0}ir}{2\pir_{0}^2}

    Explanation:

    Given that,

    Distance from the axis of the cylinder = r

    We need to calculate the magnetic field inside the cylindrical resistor

    Using formula of magnetic field

    \oint{\vec{B}\cdot\vec{dl}}=\mu_{0}i_{encl}

    B\cdot(2\pi r)=\mu_{0}\dfrac{i\pir^2}{\pi r_{0}^2}

    Where, r₀ = radius

    r = distance

    i = current

    |\vec{B}(r)|=\dfrac{\mu_{0}ir}{2\pir_{0}^2}

    Hence, The magnetic field inside the cylindrical resistor is \dfrac{\mu_{0}ir}{2\pir_{0}^2}
