Measurement and Computation of Electromagnetic Fields for Undergraduate Students

9352169 Smith-Baish拟议的实验允许学生： 1.测量磁场; 2.使用二维有限元程序对电磁源进行数值建模，并以图形方式表示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。 具体实验为： 1.为了测量诸如由于家用电器和配电或输电线路引起的磁场暴露， 2.为了计算传输线下的电场和磁场， 3.通过实验和数值计算确定不同布线配置周围的磁场，（不同设备的设计，如电热毯，将与本实验相关。） 4.通过实验和数值计算确定不同类型电机周围的磁场， 5.计算暴露于给定电场的电介质球周围和内部的电场。(This实验为电场中的生物细胞以及电场对细胞的影响提供了模型。 ***

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.) ***
