Answer :
Final answer:
The strength of the magnetic field created by a current in a long, straight wire can be calculated using B = (μo * I) / (2π * r). In this case, the strength of the magnetic field is 2.3 * 10^-5 T.
Explanation:
The strength of the magnetic field created by a current in a long, straight wire can be calculated using the formula B = (μo * I) / (2π * r), where B is the magnetic field strength, I is the current, r is the distance from the wire, and μo is a constant.
In this case, the current is 37.1 A and the distance from the wire is 40.5 cm (or 0.405 m). Plugging these values into the formula, we get B = (4π * 10^-7 T·m/A * 37.1 A) / (2π * 0.405 m) = 2.3 * 10^-5 T.
Therefore, the strength of the resulting magnetic field at a distance of 40.5 cm from the wire is 2.3 * 10^-5 T.
