永磁体的电磁加速度
Electromagnetic acceleration of permanent magnets
摘要：
我们考虑的永磁体，由钕铁硼组成的运行磁场梯度的加速。结果表明，钕铁硼中每个核子的比磁矩由物质的剩余磁化强度决定。加速永磁体的磁场的最大可达梯度由30千高斯的矫顽力决定。对于钕铁硼磁铁，这个梯度等于20千高斯除以1厘米。磁铁的有限速度是每秒6公里，加速度的长度是637米。
英文摘要：
We consider the acceleration of the permanent magnets, consisting of neodymium iron boron by means of the running magnetic field gradient. It is shown that the specific magnetic moment per nucleon in neodymium iron boron is determined by the remained magnetization of the substance. The maximum accessable gradient of the magnetic field accelerating the permanent magnets is determined by the coercive force thirty kilogauss. For the neodymium iron boron magnets this gradient is equal to twenty kilogauss divided by one centimeter. The finite velocity of the magnets six kilometers per second, the length of acceleration is six hundred thirty-seven meters.
