A．奧斯特

B．歐姆

C．法拉第

D．沈括

發(fā)現(xiàn)電流的磁效應(yīng)      發(fā)現(xiàn)安培定則          發(fā)現(xiàn)磁偏角          發(fā)現(xiàn)電磁感應(yīng)

Answer 1

A

解析試題分析：A、奧斯特最早發(fā)現(xiàn)電流的磁效應(yīng)；
B、歐姆發(fā)現(xiàn)歐姆定律；
C．法拉第發(fā)現(xiàn)電磁感應(yīng)；
D．沈括發(fā)現(xiàn)磁偏角。
A故選A。
考點(diǎn)：物理常識(shí)．
點(diǎn)評(píng)：解決此類(lèi)問(wèn)題需要掌握基本的物理學(xué)常識(shí)，平時(shí)應(yīng)注意積累．
