Difficulty of realization 8/10
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.
