[請益] 維基百科上的解釋
If a magnetic field gradient is superimposed on the uniform field,
those atoms whose magnetic moments are aligned with the field will have lower
energies in a higher field. Like a ball rolling down a hill, these atoms will
tend to occupy locations with higher field and so are called
"high-field-seeking" atoms. Conversely, those atoms with magnetic moments
aligned opposite to the field will have higher energies in a higher field,
tend to occupy locations with lower field, and so are called
"low-field-seeking" atoms.
It is impossible to produce a local maximum of the magnetic field
magnitude in free space. However, a local minimum can be produced.
This minimum can trap atoms which are low-field seeking
if they do not have enough kinetic energy to escape the minimum.
請問有人可以解釋上面的原理嗎
感激不盡
