Neodymium Plasma Vortex - 4K

The magnetic field from this neodymium ring magnet is massive compared to the ceramic ring magnet. 13,200 Gauss of the neodymium compared to about 2,000 Gauss of the ceramic ring magnet. You might notice that the arc is bulging out the front quite a bit. Not only do we have the Lorentz force acting on the moving charges particles, but the magnetic field is strong enough to interact with the magnetic field created by the current flowing through the arc. The magnetic field of the ceramic ring magnet does exert a force on the arc but it isn't strong enough to make it bulge. Of you watch the end of the first vortex video where I used the neon sign transformer, you'll see that the arc is also bulging but it's bulging because there is such a stronger magnetic field being created from the higher current that it starts interacting with the weaker magnetic field of the ceramic magnet.

Parts I Used to Make my Plasma Speaker:
1. 12V 50A Power Supply: http://amzn.to/1SqM8qd

2. Flyback Transformer: http://amzn.to/1NiRWkc

3. Ceramic ring magnet: http://amzn.to/1Sawjdq

4. Stainless steel electrodes(or tungsten). You can make them from rods found in printers. The larger, the better because small electrodes will melt.

5. Copper Grounding lugs: http://amzn.to/1VgaH05

6. Block of wood to mount the grounding lugs. http://amzn.to/1oOtSzn

7. At least 2 Logic Level MOSFETs- http://amzn.to/1RNckiZ The STP40NF10L I used are great because they have a super low Rdson at 5V and even lower at higher voltages.

8. Heatsinks - http://amzn.to/1SIhSaI Preferrably with a fan to further cool them down.

9. Heatsink compound: http://amzn.to/1VKF25j

10. NE555 Timer - http://amzn.to/25TnHfi Be wary of using other 555 variants as some are not capable of driving the MOSFETS directly.

11. 3.5mm audio cable: http://amzn.to/1MopfHL

12. Other components shown in the schematic.
