教学过程(一)导入新课1、复习电能使小灯泡发光的实验师:(板书:“电”)2、复习磁能使指南针发生偏转实验引出指南针本身就是磁铁,磁铁具有吸引铁一类物体的性质,即磁性。所以当铁钉靠近指南针时,指南针就要来吸引铁钉,所以也会偏转。3、提出研究问题:“电”和“磁”之间有联系吗?板书课题。(二)学习新课1、出示学习目标:(1)知道电流可以产生磁性。(2)电流产生 Teaching process (a) into the new lesson 1, Review of electrical energy to light a small bulb experiment: (blackboard: “electric ”) 2, review the magnetic deflection experiment led to compass leads to the compass itself is a magnet, magnet has a class of iron The nature of the object, ie magnetic. So when the nails close to the compass, the compass is necessary to attract nails, it will deflect. 3, put forward the research question: “electric ” and “magnetic ” have the connection between? (B) learning a new lesson 1, produce learning objectives: (1) know that the current can produce magnetic. (2) current generation
