一、选择题1.关于磁通量的说法正确的是A.磁通量是反映磁场强弱和方向的物理量B.穿过某面积的磁感线条数越多,则穿过该面积的磁通量越大C.穿过某面积的磁通量小,该处的磁感应强度不一定弱D.穿过某面积的磁通量为零,该处的磁感应强度不一定为零2.关于磁感应强度B、电流强度I
First, multiple-choice questions 1. About the magnetic flux argument The correct is A. Magnetic flux is a physical quantity reflecting the strength and direction of the magnetic field B. The more magnetic lines passing through an area, the greater the magnetic flux passing through this area. The magnetic flux passing through a certain area is small, and the magnetic induction intensity at that location is not necessarily weak. D. The magnetic flux passing through a certain area is zero, and the magnetic induction intensity at that location is not necessarily zero. About the magnetic induction B, the current I
