SUMMARY
The discussion focuses on calculating the magnetic field around a long straight wire carrying a current of 2.5 A at a distance of 25 cm. The relevant formula for this calculation is derived from Ampère's Law, specifically B = (μ₀ * I) / (2 * π * r), where μ₀ is the permeability of free space. By substituting the values into the formula, users can determine the magnetic field strength at the specified distance.
