Question 2: Have you noticed that when the electric fan is running, the wind from the back is usually stronger than the wind from the front?
Answer: Much weaker
Knowledge expansion: Air can flow. A small part behind and in front of the fan blades are the source of wind. The air is pushed forward by the fan blades and flows forward.
