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 […]

ELECTIC MOTOR Neodymium Magnets Rotor

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 […]

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 […]
