Do you know what this cylinder alike thing is on your Laptops charger or Usb Wires?
I am sure your answer is no. So lets share our knowledge about this cylinder.
You find this small cylinder type thing in different chargers, mouse or Keyboard's wire.
We see it everyday but never give it much value. But actually it is a useful part on our devices.
There is no board or circuit in this piece of hardware. Only wire of our hardware goes through it. It only contains two magnets which control electromagnetic waves.
When electricity is passed through wire it creates electromagnetic interference. Due to that imbalanced waves disturbance is caused. To give a balanced suppy to these electromagnetic waves this device is used.
It keeps your devices safe and secure. Its availability does not makes an extreme impact but something is better than nothing. A little error some times breaks every thing and little precaution saves you.
