Question:
A long, straight wire of length 2L on the y-axis carries a current I. According to the Biot-Savart Law, the magnitude of the magnetic field due to the current at a point (a, 0) is given by
where μ0 is a physical constant, a > 0, and θ, r, and y are related as shown in the figure.
a. Show that the magnitude of the magnetic field at (a, 0) is
b. What is the magnitude of the magnetic field at (a, 0) due to an infinitely long wire (L →∞)?
