Abstract

The initial step of a primary biological reception of low-frequency magnetic fields is considered. There are two way whereby magnetic field energy might transfer to the kinetic energy of a particle, which is postulated to be responsible for biochemical changes in living systems. The direct way has a classical analogy in the Lorentz force action on a particle. The other way is spin-related. It is found that the nuclear spin should be taken into account when a particle moves within a bounded microscopical region well insulated from ambient heat. Quantitative assessments are made of the power of different classical and quantum processes.

摘要

本文考虑了低频磁场初级生物接收的初始步骤。磁场能量可能通过两种方式转移到粒子的动能,据推测这会导致生物系统中的生化变化。直接方式在洛伦兹力对粒子的作用中有经典类比。另一种方式与自旋相关。研究发现,当粒子在与环境热良好隔绝的有限微观区域内移动时,应考虑核自旋。对不同经典和量子过程的功率进行了定量评估。
