摘要或動機

在「植物的秘密生命」這本書中提到植物在電場或磁場中會生長的更好，我最近正好學到了電磁場如何產生，以及一些產生電磁場的方法，所以本研究即利用螺形管線圈來產生均勻的電磁場，並用運用安培右手定則來控制磁場產生的方向，來探討電磁場在不同條件下對實驗植物－綠豆生長的影響。本實驗使用銅質線圈纏繞鐵碗的方式，且通入不同大小電流來改變磁場的強度，以探討對實驗植物－綠豆生長的影響。本研究所得到的結果顯示：(1)綠豆在通入電流50mA 時所產生的電磁場可促使綠豆達到最好的生長效果；(2)栽培綠豆環境中所架設的電磁場較高，可使綠豆表現出較為明顯的生長速率；(3)促進綠豆的生長並不需要二十四小時都通入電流；(4)綠豆在N 極朝上的電磁場中生長的速率較S 極朝上的磁場中要快；(5)在較低溫度環境中，電磁場促進綠豆生長的效應較為顯著。;It has been mentioned that the plants will grow faster in the electronic or magnetic field in the book of “the secret life of plants”, I learned about the knowledge and methods of how to produce the electromagnetic field just now, I use the screw wire to produce electromagnetic field and control the direction by the Amplifier’s rule to investigate the growing speed of green beans under electromagnetic field in those different temperature. In this experiment, I use the wire to screwed around the ironed bowl, and make different electric current to generate different strength of electromagnetic field, the results indicate that (1) The faster growing speed will only exist in some strength of electromagnetic field, (2) The higher ironed bowls that full of screwed wire will result in the faster growing speed, (3) It will not need electromagnetic field all days, (4) The green beans will grow fast in those north magnetic pole than those in south magnetic pole, (5)The effect of electromagnetic field to increase growing speed will be significant in higher room temperature.
