摘要
根据毕奥-萨伐尔定律推导出矩形载流线圈在空间产生磁场的计算公式.利用公式计算出两个\四个矩形载流线圈同名磁极相对时磁场分布规律.根据计算结果,设计出磁场能量转化演示仪,分析了弹体在磁场中运动特点及动能的来源.
The formula for the production of magnetic field in space by rectangular carrier coil is derived according to Safaer’s law.The formula is used to calculate the distribution of magnetic field when two and four rectangular flow line rings have opposite magnetic poles of the same name.According to the calculation results,a magnetic field energy conversion demo instrument is designed to analyze the movement characteristics of the projectile in the magnetic field and the source of kinetic energy.
