Problem

Calculate the magnitude of the magnetic field produced at a point

2.0\,\text{cm}

from a long straight conductor carrying a current of

5.0\,\text{A}

. Take

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

. a)

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

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

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

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