You can build an electricity producing kinetic energy generator using a magnetic inductor built with our 15x2.5mm disc magnets. The design of this device is by the firm Akinora who also kindly gave us permission to use their image. More information is listed below under the Details tab.
We have sold NdFeB magnets since 1996 and N42 grade since 2003, the best value for strength & temperature vs cost. Don't be fooled by claims of higher strength, N52, at lower cost.
Read the complete Google Customer Review for: "...(Indigo) N42 Neodymium magnets...the real deal…bought magnets on Amazon advertised as N52… another cheap Chinese fake"
We also provide complete Documentation including MSDS & ROHS; see below.
The kinetic energy generator provides the power for the "Magic Candle". It works on the principle of magnetic induction first discovered by Michael Faraday nearly 200 years ago.

However, they have indicated that our 15x2.5 or even 15x5mm N42 disc magnets would work as well.
