我在读书时,看到摩擦起电很神奇,可以吸住一些细小的东西。真的有这么神奇吗?我想做个实验,试试看。

When I was reading, I saw that friction induced electricity is amazing, it can suck up small things. Is it really that magical? I want to do an experiment and give it a try.

我迫不及待地准备做实验所用的材料:一支塑料钢笔和一些碎纸片。实验开始了,我拿起笔杆快速地在头发上摩擦,当摩擦到我头皮都热的时候,我迅速地拿起笔杆,慢慢地靠近纸屑,我想,奇迹会不会发生呢?我屏住了呼吸,瞪大了眼睛,等待着奇迹的到来,当笔杆靠近纸片一两厘米的时候,奇迹真的发生了。碎纸片像长了翅膀一样,“飞”了上去,粘在了笔杆上。啊!太神奇了!

I can't wait to prepare the materials for the experiment: a plastic pen and some shredded paper. The experiment started. I picked up the pen holder and quickly rubbed it against my hair. When the friction made my scalp hot, I quickly picked up the pen holder and slowly approached the paper scraps. I thought, will a miracle happen? I held my breath, widened my eyes, and waited for a miracle to come. When the pen holder was one or two centimeters close to the piece of paper, the miracle really happened. The shredded paper looks like wings; Fly” It went up and stuck onto the pen holder. Ah。 It's amazing!

为什么会出现这种现象呢?我向“度娘”发起了问号。摩擦起电是电子由一个物体转移到另一个物体的结果,使两个物体带上了等量的电荷。得到电子的物体带负电,失去电子的物体带正电。因此原来不带电的两个物体察擦起电时,它们所带的电量在数值上必然相等。摩擦过的物体具有吸引轻小物体的现象。

Why does this phenomenon occur? I am speaking to“ Du Niang; Initiated a question mark. Frictional electrification is the result of electrons transferring from one object to another, causing both objects to carry an equal amount of charge. An object that gains electrons carries a negative charge, while an object that loses electrons carries a positive charge. Therefore, when two uncharged objects are observed to be electrified, the amount of electricity they carry must be numerically equal. Rubbing objects have the phenomenon of attracting light and small objects.

像这样神奇的事情,还有许多,需要我们善于观察,这样就会发现生活中更多的奥秘。

There are many magical things like this that require us to be good at observing, so that we can discover more mysteries in life.
