Hi! Everyone. I encounter some trouble in deriving the kernel of Laplace equation with prescribed boundary conditions.
Given the following preposition:
$$T(x, y) = \int_{-\infty}^{\infty}dx'\frac{y/\pi}{(x-x')^{2}+y^2}F(x')...[1]$$
satisfies the Laplace equation for ##x\in(-\infty, \infty)##...
Hi! My high school physics tells me using right hand grip rule to determine the direction of magnetic field induced by a current carrying wire, but I wonder whether I can deduce the direction merely from Maxwell's Equations?
Suppose now we have a current density in cylindrical...
