Measurement and Computation of Electromagnetic Fields for Undergraduate Students

9352169 Smith-Baish提出的实验允许学生：测量磁场；2. 利用二维有限元程序对电、磁源进行数值模拟，并用图形表示这些源产生的电场和磁场；和3。比较实验和理论磁场测量值。具体的实验有：1。测量磁场暴露，如由于家用电器和配电或输电线路；计算输电线路下的电场和磁场；以实验和数值方式确定不同布线结构周围的磁场，（电热毯等不同设备的设计将与此实验有关。）4. 通过实验和数值方法确定不同类型电机周围的磁场；计算在给定电场作用下介电球周围和内部的电场。（本实验为电场中的生物细胞和电场对细胞的影响提供了一个模型。）* * *

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.) ***
