磁场强度等于电流乘以导线长度?
Current length
这里是我在书上看到的 current length :a relative measure of the magnetic field strength produced by a length of wire carrying current and equal to the product of the current and the length.还是没搞懂

磁场强度不等于电流乘以导线长度,物理学中有磁场强度的物理量,出现在有磁介质情况下的磁场描述当中,如果你指的是磁场强弱就不应该用磁场强度的概念.
实际上磁场的强弱是用磁感应强度来衡量,定义式为:
B=F/IL
Current length 电流长度
这可能说的是,作为一个相对测量,某点A固定,与电流的导线的角度也固定,那么A点的磁场B,与IL成正比,这是毕奥-萨伐尔定律,上述条件固定后,其余与磁场有关的量都是常数,只与IL有关,于是就用IL表示磁场强弱.可见这里说的是电流产生的磁场,而不是说电流放到磁场中来测量磁场!
Current length 当前长度
它定义为磁通密度[1]B除以真空磁导率μ0再减去磁化强度M,即 -M
H为矢量。这样,在恒定磁场中磁场强度的闭合环路积分仅与环路所链环的传导电流Ic有关而不含束缚分子电流,即
