This rotation is really fast. I do not know how many there are RPMs, some suggest me a method for determining the speed of rotation? The principle of operation is always that of the classic homopolar motor , but in this experiment are able to reduce to a minimum the friction and the speed increases […]

It may seem complicated, but the operation of this magnetic experiment is very simple. All the supporting structure is made of metal and therefore conduct current up to megnets at the ends of the rotor. When these neodymium magnets are in contact with the end of the copper coil, the circuit closes and the copper […]
WARNING!!! This experiment can be dangerous, I recommend anyone to try it without nails WOW, I discovered this magnetic effect almost by chance by testing for another experiment. it is amazing how fast the arrow is shot from the magnets with hole. To obtain the weapon effect, the arrow and the launcher must have the […]
You’re in the dark and without electricity? With just a few ingredients you can make a flashlight. It takes a copper coil, a tube, a LED light and of course a powerful neodymium magnet. And electricity? It is in your hands.
Another variant of the homopolar motor. This time I create the necessary short circuit to activate the motor with a copper wire or iron. Fun science experiment For this experiment i have used Duracell Rechargeable battery http://amzn.to/2mcLGHQ i use 2 neodymium magnet 20x3mm and 2 magnet 15x5mm with hole a rechargeable battery copper wire iron […]
This experiment has been challenging, but in the end gave me satisfaction. The operation is not exactly the same as the real MAGLEV but a little like us. Between the train and the rails there is magnetic repulsion bound by two transparent plates attached to the train. The rails is 3 meters long and used […]
After a long time I went back to play with the magnetic balls. Zen magnets, buckyballs, neocube, call it what you want but are great fun and allow you to do amazing magnetic sculptures.
Not talking about high definition audio, but it’s surprising how easy it is to create a speaker to build headset. Need only an enameled copper wire, a strong neodymium magnet and a plastic cup. The magnet vibrates the coil of copper when it passes the current, this vibration is amplified by the plastic cup. Fun […]
OK, the free energy do not exist, but this experiment has something magical that makes me think of infinite energy. To speed up the disk needs a path to follow of least resistance. I trace the route moving slowly the ring. I pass the energy from my hands to the rotor with the movement of […]
