[領域]靜磁 (題目相關領域) [來源]台大考古題版看到的 (課本習題、考古題、參考書...) [題目] A long cylinder of radius R with charge density ρ(s) = a/s rotates around its axis, the z-axis, with angular velocity ω.(a is a constant) The permeability of the cylinder is μ. Find the vector potential A inside and outside the cylinder, assume ▽．A = 0. [瓶頸] (寫寫自己的想法，方便大家為你解答) 利用∮A．ds = ∫B．da 而對於ds，電流為(a/s)*2πsl*(ω/2π) 但不知道怎麼求磁通量，因我認為柱面上的電流會互相干擾煩請高手為我解惑 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 218.162.108.239
