如圖所示,將長(zhǎng)50cm、質(zhì)量為10g的均勻金屬棒ab的兩端用兩只相同的彈簧懸掛成水平狀態(tài),位于垂直紙面向里的勻強(qiáng)磁場(chǎng)中,當(dāng)金屬棒中通過(guò)0.4A的電流時(shí),彈簧恰好不伸長(zhǎng),求:(g取10m/s2)                     

(1)勻強(qiáng)磁場(chǎng)中磁感應(yīng)強(qiáng)度是多大?                                                                        

(2)當(dāng)金屬棒中通過(guò)0.2A由a到b的電流時(shí),彈簧伸長(zhǎng)為1cm,如果電流方向由b到a,而電流大小不變,彈簧又伸長(zhǎng)是多少?
