Claim:
1. A fan device comprising: two spaced-apart magnetic members arranged such that one side of one of said magnetic members faces one side of the other one of said magnetic members and has a magnetic polarity opposite to that of said one side of said the other one of said magnetic members, said magnetic members defining a magnetic field therebetween; a fan disposed between said magnetic members, and including a rotatable hub and a plurality of angularly spaced-apart fan blades that radiate from said hub; and a wire mounted on said fan, and having two distal electrode ends and a plurality of induction portions, each of said induction portions being coupled to a respective one of said fan blades, and being co-rotatable with the respective one of said fan blades to intersect the magnetic field to thereby generate an induced current that flows toward said electrode ends of said wire, wherein: said hub of said fan is rotatable about a central axis; each of said fan blades has opposite top and bottom edges extending from said hub, and a lateral edge interconnecting distal ends of said top and bottom edges which are distal from the central axis; and each of said induction portions of said wire being coupled to said lateral edge of the respective one of said fan blades, and having an end that is registered with an intersection between said lateral edge and said top edge of the respective one of said fan blades, and an opposite end that is registered with an intersection between said lateral edge and said bottom edge of the respective one of said fan blades.
