想問最上面題組一怎麼看正電負電

一、題組 1. 如下圖所示,粒子由甲、乙、丙、丁四個方向射入垂直磁場中,試回答下列問題: (B) (1)粒子從甲方向,由西向東水平射入磁場,若粒子向北彎曲,則子帶什麼電? (A)帶正電(B)帶負電(C)不帶電(D)正負電都帶(E)正電或負電均可能 (B) (2)粒子從乙方向,由北向南水平射入磁場,若粒子方向不變,則粒子帶什麼電? (A)帶正電(B)帶負電(C)不帶電(D)正負電都帶(E)正電或負電均可能 。 。 。 (A) (3)帶負電粒子從丙方向,由東向西水平射入磁場,則因磁力作用,粒子會向何方彎曲? (A)向上方彎曲(B)向下彎曲(C)向北方彎曲(D)向南方彎曲(E)不彎曲 (4)帶正電粒子從丁方向,由南向北水平射入磁場,則因磁力作用,粒子必會向何方彎曲? (A)向上方彎曲 (B)向下彎曲(C)向東方彎曲(D)向西方彎曲(E)不彎曲 (D) 甲 甲 上北 乙 N 内西 南下 JS 東 ? →[ I 。 2.無限長直導線通以電流I,如上圖右,甲、乙、丙、丁為4個不同位置,與導線的距離均相同且共 平面,則: ( ) (1)關於甲、乙、丙、丁的磁場方向敘述,下列哪些正確?(多選) (A)甲、丙處的磁場方向相同(B)甲、乙處的磁場方向相反 (C)甲、丁處的磁場方向相反 (D)丙、丁處的磁場方向相同 (E)甲、乙、丙、丁處的磁場方向均相同 。 ( ) (2)若導線的電流增為2I,其方向變為向左,則下列哪些正確?(多選) (A)甲處磁場變大,乙處磁場則變小(B)甲處磁場方向為 (C)乙處磁場方向為 (D)丙、丁兩處的磁場方向與量值均相同(E)甲處磁場量值為丁處磁場量值的2倍 O , 3. 悠遊卡與讀卡機的構造可視為圖(一)。由讀卡機供應電流II產生磁場,悠遊卡中則有線圈連結著 晶片,形成一個迴路。平常悠遊卡中因為沒有電源,所以沒有電流,但當悠遊卡靠近讀卡機時 I1產生的磁場會使悠遊卡中的線圈有感應電流I2。【113.全國模考】 悠遊卡 晶片 磁力線 讀卡機 圖(一) 12 圖(二) →1 ( ) (1)若欲使更多的磁力線穿過悠遊卡中線圈,下列作法哪些正確?(應選2項) (A)將讀卡機的電流減少(B)將悠遊卡更靠近讀卡機 (C)將悠遊卡離讀卡機更遠一些(D)讓悠遊卡中的線圈平面與讀卡機中的線圈平面垂 直(E)增加悠遊卡中的線圈平面之面積, 。 ( ) (2)將圖(一)中的電流方向定義為II、I2之正方向,若希望悠遊卡中持續有感應電流I2,且與 時間t的關係如圖(二)所示,則讀卡機的電流I與時間t之關係圖形應為下列何者? (A) // (B) 4 1 □ 大學先修課程(EWANT) □ 其他(靜宜參訪紀錄) (C) 4 A
