By utilizing the magnetic field and energy conversion, magnetic turbines convert mechanical energy into electrical energy. In a magnetic turbine, the rotating magnets create a changing magnetic field, which induces an electric current in the nearby coil.

No, gravity can not be used as an infinite energy source. In fact, strictly speaking, gravity itself can not be used as an energy source at all. You are confusing forces with energy, which are very different things. Energy is a property of objects, such as balls, atoms, light beams, or batteries.
