9352169 Smith-Baish The proposed experiments allow students to: 1. measure magnetic fields; 2. numerically model electric and magnetic sources using a two- dimensional finite-element program, and graphically represent the electric and magnetic fields generated by these sources; and 3. compare the experimental and theoretical magnetic field measurements. The specific experiments are: 1. to measure magnetic field exposures such as those due to household appliances and distribution or transmission lines, 2. to calculate the electric and magnetic fields under transmission lines, 3. to determine experimentally and numerically the magnetic fields around different wiring configurations, (The design of different devices such as electric blankets will be related to this experiment.) 4. to determine experimentally and numerically the magnetic fields around different types of motors, and 5. to calculate the electric field around and in a dielectric sphere exposed to a given electric field. (This experiment provides a model for a biological cell in an electric field and the effect of the electric field on the cell.) ***

9352169史密斯-拜什提出的实验允许学生：1.测量磁场；2.使用二维有限元程序对电和磁源进行数值建模，并以图形表示由这些源产生的电场和磁场；以及3.比较实验和理论磁场测量结果。具体的实验是：1.测量家用电器和配电或输电线路引起的磁场暴露，2.计算传输线下的电场和磁场，3.通过实验和数值确定不同布线配置周围的磁场，(电热毯等不同装置的设计将与本实验相关)4.通过实验和数值确定不同类型电机周围的磁场，以及5.计算暴露在给定电场下的介质球周围和内部的电场。(本实验提供了电场中的生物细胞的模型以及电场对细胞的影响。)*
