如图为“研究电磁感应现象”的实验装置，电键合上前小螺线管已插入到大螺线管中。

（1）将图中所缺的导线补接完整；

(2)如果在闭合电键时发现灵敏电流计的指针向右偏转一下，那么合上电键后将小螺线管迅速抽出时，灵敏电流计指针将向      (“左”或“右”)偏转。

解析：

(3)小螺线管插入大螺线管后，将滑动变阻器触头迅速向左移动时，灵敏电流计的指针将向

      (“左”或“右”)偏转。

Beyond question, Clinton was supposed to close up, stay out of sight, and avoid second- guessing his wife’s boss. After his ego blustered into oncoming traffic during Hillary’s heated primary race (1) Obama, the nation suffered from yet another turn of Clinton fatigue.
