http://wiki.answers.com/Q/H...an_electric_fan_workQ: How does an electric fan work?
A: An electric fan is an electric motor with a fan blade attached to the rotating shaft. As the motor spins, the fan blades rotate. Each blade is inclined a bit, and as the inclined plane of the blade moves through the air, it forces the air ahead of it forward. Each blade does this on a continous basis, and the result is a moving air stream. The fan is taking air
(Sucking) from the area behind itself and
blowing it out the front. The fan generates a movement of air, causeing the warm, less dense air to rise, and the cool, dense air to descend. Thus the coolness now in the air.
