A long, straight wire in vacuum carries I=12 AI=12\,\text{A} upward. Point PP lies d=0.040 md=0.040\,\text{m} from the wire. Use the Biot-Savart result for an infinite wire: B=μ0I2πdB=\dfrac{\mu_0 I}{2\pi d} with μ0=4π×10−7 T⋅m/A\mu_0=4\pi\times10^{-7}\,\text{T}\cdot\text{m/A}. What is the magnitude of the magnetic field at point PP due to the wire?
