2. A Helmholz coil is a simple method for generating fairly constant magnetic fields at a point when a solenoid is not available or would not be convenient. A Helmholtz coil consists of two parallel coils of wire, each with N loops, and each of a radius a and separated by a distance a too. For this problem, let the $z$-axis be the common axis of the loops, and let one loop be in the $z = -\frac{1}{2}a$ plane and the other be in the $z = \frac{1}{2}a$ plane. The same counterclockwise current $I$ flows in both. a. What is the magnetic field, $\vec{B}(\vec{r}) = B(z)\hat{z}$, at a point $\vec{r} = z\hat{z}$ between the two loops? $\frac{dB}{dz}$ and $\frac{d^2B}{dz^2}$ at the point midway between the two loops, which here is the origin, $z = 0$. c. Does this result suggest that the field is fairly uniform in the region near $z = 0$?
