Key Equations

$$B_r = -\frac{2\mu_0 M_E}{4\pi r^3}\cos\theta, \qquad B_\theta = -\frac{\mu_0 M_E}{4\pi r^3}\sin\theta$$
$$\left[\rho v_n^2 + p + \frac{B_t^2}{2\mu_0}\right] = 0 \qquad \text{(normal momentum)}$$
$$v_{in}^2 = \frac{v_A \eta}{L} \quad \Rightarrow \quad \boxed{\frac{v_{in}}{v_A} = \frac{1}{\sqrt{R_m}} = \frac{1}{\sqrt{S}}}$$
$$J_y = \frac{1}{\mu_0}\frac{dB_x}{dz} = \frac{B_0}{\mu_0 \delta}\text{sech}^2\left(\frac{z}{\delta}\right)$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
