[題目] 電磁學的題目
[領域]電磁學 (題目相關領域)

[題目]A dielectric cylinder of radius A rotates about its axis with a constant
angular velocity w.There is a uniform magnetic field B also parallel to the
axis.Find the dielectric polarization of the cylinder.
[瓶頸] (寫寫自己的想法，方便大家為你解答)
覺得應該是極化產生的表面電荷因旋轉所產生的表面電流 會對裡面
產生一個磁場 這個磁場跟原施加磁場B加起來再圓柱內某一點的
作用力會跟內部極化的電荷密度所產生的電場的力大小相等方向相反
不知道是否有出錯 還有解法該怎麼寫 謝謝各位大大了
