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

Hol sin 0 dy, B(a) 4т --

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 MoIl B(a) 2п аVa? + 1

b. What is the magnitude of the magnetic field at (a, 0) due to an infinitely long wire (L →∞)?
