摘要

对垂直下落的蒸馏水射流在永磁磁场作用下的偏转进行了实验和理论研究。射流底部直径d = 1.1±0.05 mm的水射流被永磁体产生的强度B = 0.63±0.03 T的磁场偏转。当B(x) = B0e -λx, B0 = 0.66 T时，实验确定了水射流的平均角偏转为θ (5.0 × 10-3 rad) = 0.3°；λ = 0.123 m-1；|∂B/∂x| = 70 - 80t /m。提出了该效应的半定量理论，与实验结果吻合较好。这种效应来自于将抗磁性体推出梯度磁场的体积力。讨论了该效应的应用。

Magnetic Field Deflects Water Jet

Deflection of a vertically falling jet of distilled water by a permanent magnetic field was studied experimentally and theoretically. Water jet with a diameter at the base of the jet d = 1.1 ± 0.05 mm was deflected by the magnetic field of intensity B = 0.63 ± 0.03 T produced by a permanent neodymium magnet. The average angular deflection of the water jet was experimentally established as θ ≅ 5.0 × 10^–3 rad ≅ 0.3° for B(x) = B₀e^–λx, B₀ = 0.66 T; λ = 0.123 m^–1; |∂B/∂x| ≅ 70–80 T/m. Semiquantitative theory of the effect is suggested, which is in satisfactory agreement with the experimental findings. The effect emerges from the bulk force, which pushes the diamagnetic body out of the gradient magnetic field. Applications of this effect are discussed.
