Each air blade 11 suffered magnetic force f can use following equation expression:
f = mm ′ 4 π μ 0 r 2 = 6.3 × 10 4 × mm ′ r 2 - - - ( 1 )
In following formula (1), m represents the permanent magnet magnetic charge, and m ' is the electromagnet magnetic charge, and r is the distance between electromagnet and the permanent magnet.
Wherein, after employed permanent magnet 20 was selected, m was a constant, and m ' and r are variablees during the wind wheel rotation, and these three parameters have determined the size of f together.And the size of f is directly proportional with mm ', with r 2Be inversely proportional to.Therefore it is little when big that wind wheel 10 is subjected to when being, constantly change, clocklike, the circuit magnetic force, this magnetic force can be decomposed into along the rotating force of wind wheel 10 rotation round tangent directions and to the magnetic buoyancy that wind wheel 10 makes progress, and promotes wind wheel 10 rotations jointly.
