1教具装置图(见图1)2仪器特点及用途(1)特点组合发电机使用的主要材料是有机玻璃板,既保证了一定的牢固度又容易加工。而且由于有机玻璃板是透明的,因此可以使学生非常直观地观察到组合发电机的内部结构,从而达到更好的教学效果。另外,此教具操作简单,效果明显,成功率高,可以重复使用。(2)用途当线圈的匝数一定时,磁通量的变化越快,感应电流的强度越大。当线圈中的磁通量增大或是减小时,感应电流的方向相反。当线圈中的磁通量的变化速率相同时,线圈
1 teaching aids device diagram (see Figure 1) 2 features and uses of the instrument (1) Features The main material used in combination generator is plexiglass plate, both to ensure a certain degree of firmness and easy processing. And because the plexiglass plate is transparent, so you can make students very intuitive to observe the internal structure of the combined generator, so as to achieve better teaching results. In addition, the teaching aids are easy to operate, the effect is obvious, the success rate is high, and can be reused. (2) Use When the coil turns a certain number, the faster the change of magnetic flux, the greater the intensity of the induced current. When the magnetic flux in the coil increases or decreases, the direction of induced current is reversed. When the rate of change of magnetic flux in the coil is the same, the coil
