Webmagnetic field B which obeys the same equation B 0 (6.1) as its microscopic analog. Then we can still use the concept of a vector potential A whose curl gives B. In the presence of a magnetic field, matter becomes magnetized; that is the dipoles acquire a net alignment along some direction. WebYou remember that the vector potential function has some arbitrariness. Two different vector potential functions $\FLPA$ and $\FLPA'$ whose difference is the gradient of some scalar function $\FLPgrad{\psi}$, both represent the same magnetic field, since the curl of a gradient is zero. dean parish council https://insursmith.com
