题目:

法拉第通过静心设计的一系列试验,发现了电磁感应定律,将历史上认为各自独立的学科“电学”与“磁学”联系起来。在下面几个典型的实验设计思想中,所作的推论后来被实验否定的是[ ]

A.既然磁铁可使近旁的铁块带磁,静电荷可使近旁的导体表面感应出电荷,那么静止导线上的稳恒电流也可在近旁静止的线圈中感应出电流

B.既然磁铁可在近旁运动的导体中感应出电动势,那么稳恒电流也可在近旁运动的线圈中感应出电流

C.既然运动的磁铁可在近旁静止的线圈中感应出电流,那么静止的磁铁也可在近旁运动的导体中感应出电动势

D.既然运动的磁铁可在近旁的导体中感应出电动势,那么运动导线上的稳恒电流也可在近旁的线圈中感应出电流
