This is my first post on Steemit but I'd like you give to up vote my post.........
You know why we're all little we use to do this stuff like probably most times I the morning after we've creamed our hair in our Schools. We rub our Biro on our hair very quickly and tough then after that we cut a little piece of paper and put the Biro close to and you see an attraction that pulls the paper to the Biro. But most people don't really know the physics behind it, so I'd like to let you know.
The physics behind it is that if you probably try rubbing the Biro on your hair in a very very dark room you'll observe a little spark which I call lightning to make it look fancy then after observing that then move the Biro close to your small piece of paper you'll observe another little spark...
Then what is the spark called and the force between the paper and your Biro......
- The spark is called Electromagnetic force.
What is Electromagnetic force?
- This is a magnetic field that is produced by acurrent of electricity.
The force between the paper and the Biro is called Frictional force.
What is Frictional force?
This is the act of rubbing one thing against another
I hope you guys gave learnt some thing
