论文摘要
根据Blackett的猜想，任何中性旋转的身体都获得与其角动量成比例的磁矩。使用火星的偶极磁场上的数据，我们对Blackett常数的值进行了严格的上限，该值将磁矩与角动量相关联的无量纲常数。结果，布莱克特效应无法直接考虑天体和星系的磁场。我们还表明，黑色效果无法在实验室中进行测试，因为任何旋转的实验室尺度对象的磁矩将比众所周知的Barnett效应产生的物体小得多。
According to the Blackett conjecture, any neutral rotating body acquires a magnetic moment proportional to its angular momentum. Using the data on the dipolar magnetic field of Mars, we put a stringent upper limit on the value of the Blackett's constant, the dimensionless constant that relates the magnetic moment to the angular momentum. As a consequence, the Blackett effect cannot directly account for the magnetic fields of celestial bodies and galaxies. We also show that the Blackett effect cannot be tested in a laboratory since the magnetic moment of any rotating lab-scale object would be much smaller than the one produced by the well-known Barnett effect.
