The video shows that magnets alone can be so configured to produce usable electrical energy output.

It should be noted that the strength of the magnets and their interaction must provide an energy input in horsepower (fractional in this instance) that exceeds the resistance of the load.  In other words, if the magnets are capable of inputing .015 horsepower of energy into the interaction between the stationary magnet and the wheel-mounted magnets,  the load cannot require more than ~ .01 horsepower, or the counter Electro-Motive-Force (EMF) generated in the motor coils will stop the motor rotor shaft from spinning thus stopping the magnet wheel from spinning.

 

 
Build one, sit it on your desk, see if you can live long enough to see the magnets wear out. 

[the friction of operation at the bearing surfaces will lock the motor rotor down long before the magnets "wear out."  That's why these magnets are called "permanent" magnets].

 
PARTS - MATERIALS  --
 
DC Motor:  $2.00  1.5VDC - 3.0VDC  (lower RPM better)  [get one out of an old toy]
 
Disk Mounted Magnets: [1/8" Cube] 10-49  $0.24 each  (Minimum = 10)
 
Drive Magnet: [1" x 1" x .5"] 1-19  $2.75 each  (Minimum = 1)
 
Krazy Glue (SuperGlue):
4" Diameter Plastic Disk:
LED:  (Radio Shack)
Wire:
Solder:
Mount:  Match Sticks

All disk-mounted magnets must have either All North or All South Magnetic poles pointing OUT.

That's away from the circumference edge of the disk.

You don't have to notch the edge of the disk where the magnets are mounted.  The magnetic field of each disk-mounted magnet will penetrate the plastic as if it were invisible.
