Example 1: Calculating the Magnetic Field due to a Current in a Straight Wire. A long, straight cable in an industrial power plant carries a direct current of 100 A. Calculate the strength of the resulting magnetic field at a perpendicular distance of 0.06 m from this cable. Use 4 𝜋 × 1 0 T⋅m/A for the value of 𝜇 .
