WIND MILL
________________________________________________________________________
A device used to convert wind energy into mechanical energy is called windmill.
Construction: It consists of a wheel with blades cut into its outer rim . The wheel rotates about an axle mounted on a pole. The wind energy is used to rotate the wheel about its axle.
Uses : Wind mill is used for operating water pumps, grinders and is also used to produce electricity.
Wind mill for producing electricity ( wind generator ) : Electricity is produced when an armature of a generator rotates between two poles of a strong magnet. When wind falls on the wheel of a windmill, it rotates. The axle of the armature is connected to the shaft of the windmill. So the armature of the generator rotates between two poles of a magnet along with the rotation of the wheel of the windmill.
Thus, electric current is produced. This is how the kinetic energy of the wind is converted into electrical energy.
You can make a setup of windmill and can show how does it work .
