Calculate the magnitude of the magnetic field at a point

2.0\,\text{cm}

from a very long straight conductor carrying a current of

5\,\text{A}

. Take

\mu_0 = 4\pi \times 10^{-7}\,\text{T m A}^{-1}

. (a)

5.0 \times 10^{-4}\,\text{T}

(b)

5.0 \times 10^{-5}\,\text{T}

(c)

2.5 \times 10^{-5}\,\text{T}

(d)

1.6 \times 10^{-5}\,\text{T}
