Without the fans blades you may get a balance issue, out of line spinning. You could use some thing as a counter weight. Just like balancing car tyres.
You could make four of these and use them under a large tank of some kind to investigate magnetism. Magnets are dipoles. You could attach two of your stirrers side to side and make them spin in opposite directions. Attach them far enough apart so each vortex can exists nest to the other. Make two of those units and one can demonstrate what happens when two magnets are put next to each other in different pole configurations.
True Free energy devices exist,But there are very powerfull forces that want to supress the technology,Get a REAL working magnet motor at LT-MAGNET-MOTORdotCOM ,Be a part of the energy revolution!
@starshock01 the blades also help balance it, if you broke or cut them off you would have to make sure you get them all the way down to the base, that plus you would need to make sure you're magnet is balanced in the middle of the fan. It's easier just to leave the blades on.
@starshock01 I wouldnt remove fan blades since fan is already rotating on high RPM compared to comercial stirers, so removing blades wold just make it faster...
If someone had the time they could balance the magnet on top with the fans cut off. On another video of a home made stirrer he/she used two O ring magnets which would have been easier to balance.
hi i made one but before i saw this vid, it a good video and a good magnetical stirer but you should have a potentiometer hookt in the cuircet so you could vary the speed ;) i have that and i woks great :)
LOL, I've also built myself some kind of magnetic stirrer using an old PC fan, but mine is by far not as cool as yours, so 5* from me!
But one thing I've always been wondering: If you place a strong magnet directly on top of the electric motor of the fan, why doesn't it get any affection?
Really? Mine goes a little slower too, but I've been interpreting that as a result of the extra weight. I didn't place the magnets directly above the fan in my last construction, I put an alu tube between and fixed them with epoxide glue (that was necessary so I can heat from the side). But I can operate the device with max. 5V, if I use 12V the stir bar won't follow the rotation anymore but rather fall into some kind of tremor state :D so I think my magnets aren't strong enough
I would highly recommend buying some real stir bars depending on what you want to stir, they are usually plastic coated for corrosion resistance and a little more durable. A 5-10 pack of assorted sizes should run you about $1 each.
As suggested below variable speed might be nice, depending on how fast the fan goes in the first place.
Keep them coming and enjoy giving your hand a rest from stirring and shaking.
Good work, I have also a homemade stirrer made in few months ago, so I am planning to film video about it. Mine has a bit different from yours, mine is portable which powered by 12V Lead-acid battery and have speed control by rheostat.

seeing how glass is quite easy to break you should try to find a peace of Plexiglas to replace the glass, just a thought i had

why does no one remove the fan blades? it would save a bunch of energy just blowing air in a circle...

@starshock01 I'ts actually going too fast as it is, that's why I built a new one with a potentiometer

put a potentiometer, to control the speed, that's way more important than a led

@dbc616 What about PTFE coated stirrer?

Great idea, but you should have clipped off the fans. It adds useless resistance to the motor.
Now that I think about it the fans could equalize the weight of the magnet on top, but I am not sure. What do you think?
AWIERD1 2 years ago
I don't think they equalize the weight, but I think they add stability to the motor.

Thanks! About the electric motor... IT DOES. it goes about 1/4 the speed when the magnet is on it.

The computer fan is a 12V fan, so I don't think 5V will work. The AC adapter that I have converts 120V AC to 12V DC.
dbc616 2 years ago
Try it! I've got mine hooked up on an old computer PSU and I can vary the fan speed by changing voltages (3,3V, 5V, 7V, 12V)
bla287 2 years ago
Maybe i will, that's awesome. I could get some kind of dial to change the speeds.

if you replace the on/off swichh with a variable resistor from say a light switch or cd player you could make it have variing speeds.
