SUMMARY
A long straight wire carrying a current of 2 amps creates a magnetic field determined by the formula B = μ₀I / (2πr). In this case, μ₀ is 4π × 10⁻⁷ As, and the distance from the wire is 0.5 m. The angles mentioned in the discussion (30 degrees W of N and 60 degrees S of W) do not affect the calculation of the magnetic field strength. The magnetic field strength at the specified distance is solely dependent on the current and the distance from the wire.
