Magnetic field due to currentHard
Question
A wire carrying a current I is bent into the shape of an exponential spiral, r = eθ, form θ = 0 to θ = 2π as shown in figure. To complete a loop, the ends of the spiral are connected by a straight wire along the x-axis. Find the magnitude of B at the origin.
