在电磁学中,有两个相似情景的问题,即磁流体泵和磁流量计,它们都是电磁问题,均以霍耳效应为背景.但其模型及规律完全不同,现比较分析如下: 1.在原子反应堆中抽动液态金属或在医疗机器中抽动血液等导电液体时,由于不允许传动的机械部分与这些液体接触,常使用一种磁流体泵,如下表中图A表示这种磁流体泵的结构,将导管放在磁场中,当电流通过导电液体时,这种液体即被驱动,如果导管截面面积为
In electromagnetics, there are two problems with similar scenarios, namely magnetic fluid pumps and magnetic flowmeters. Both of them are electromagnetic problems. They all use the Hall effect as the background. However, their models and laws are completely different. The comparative analysis is as follows: 1 When a liquid metal is twitched in an atomic reactor or a conductive fluid such as blood is hauled in a medical machine, a magnetic fluid pump is often used because the mechanical part of the transmission is not allowed to come in contact with the liquid. This magnetic fluid is shown in Figure A in the following table. The structure of the pump, the catheter is placed in a magnetic field, when the current through the conductive liquid, the liquid is driven, if the catheter cross-sectional area
