6. Magnetic levitation
• A method by which an object is suspended in air with no support
other than magnetic fields. Here magnetic pressure is used to
counteract the effects of the gravitational forces.

8. Working principle
• The kinetic energy from wind is captured by the blades. The
blades start to rotate and spin a shaft that leads from the hub of
the rotor to a generator and produce electricity .
• Using the effects of magnetic repulsion, wind turbine blades
fitted on a shaft during rotation remain suspended as a
replacement for ball bearings which are normally used on
conventional wind turbines

10. Advantages over conventional wind
turbine
• Less Vibrations-we can mount anywhere including on your house roof
• Less Noisy-quiet enjoyment of living
• The equipment has longer life due to no wear & tear
• Strong adaptability-can be used for land, beaches, weak offshore wind.
