Step 1: Levitation of Homopolar Motor

I joined the homopolar motor experiment with the pencil levitation experiment ... and this is the result. I think it is an original work, you have seen one like it around on web? It is similar to the experiment of the Mendocino motor, but in this experiment the movement is produced by a homopolar motor.

Step 2: How to Make

The hardest part is to create a well balanced rotor combining neodymium magnets, iron pipes and battery.

I used polystyrene base with neodymium magnets 30x3mm inserted into the base.

For the rotor:
1) a new rechargeable battery
2) magnetic disk with a hole 15x5mm near the battery and close the screw,
3) 2-iron tubes of 15mm diameter
4) other magnets neodymium 20x2mm at the ends that make levitate the rotor
5) a screw
6) a copper wire to put the battery in short circuit

All magnets are grade n42 first of all advice to build the rotor with the pieces that found, constructed after the base by adapting it to the dimensions of the rotor. more the rotor is longer and more stable ... but do not go overboard with the weight.

the polarity of the magnets near the battery is very important. I try to outline the position.

    Is it using up the battery's life? And how long can the turning continue?

    the batteries in short-circuit lasts about 3-4 minutes, although they are not fully discharged, must be recharged.

    Gee, that's all? Did you try putting in a series resistor? I don't think you need maximum current due to the low friction. Draining a battery this fast is definitely bad for the battery anyway.

    Yes, the batteries short-circuit quickly decay. I could try to put a resistor on copper wire, put resistor on the rotor may be difficult.

    Yes, I meant on the wire. On the battery wouldn't work. It would rotate and come out of contact with the wire. You could also move the straight part of the wire closer to the battery to get a higher magnetic field at a reduced current.

    Awesome idea! Buona idea! Perché non aggiungere più dettagli sui pesi e links ai magneti?

    Grazie, si, ho visto che mediamente gli instructables sono un po più dettagliati di come ho fatto io. Ho cominciato ad aggiungere qualche info importante sulla polarità dei magneti.

    Youtube analytics mi ha detto che qualche click al mio video arrivava da questo sito ... è cosi' che mi hai fatto conoscere questo sito :-)

    Si vede. E` molto migliore adesso. Ho dimenticato di Youtube analytics. Sono contento che hai trovato questo sito cosí.

    I can see that. It is much better now. I forgot about Youtube analytics. I'm glad you found this site that way.
