【摘要】 针对普通物理学中螺线管模型不能说明的无限长载流密绕螺线管外的磁感应强度不为零的问题,提出建立与实际更接近的螺线管模型,进而计算出其全空间的磁感应强度。更多还原

【Abstract】 Actually,magnetic mduction is not zero for unlimited length solenoid holding current.This viewpoint can not be explained by soleniod model in genera physics.The object of this thesis is to establish more practical solenoid model and calculate total space solve of magnetic induction.更多还原
