Brown creates an iron tornado forming different figures: "It's beautiful"
For this experiment we have inserted a set of large neodymium magnets (neodymium magnets are the permanent type of magnet of greatest power that exists) on an album attached to the axis of an engine step by step of great power, which will allowThat the magnet set turns at high speed.The engine set and the magnets is installed under a thin layer of methacrylate on which we will throw a handful of steel nails.
The distribution of magnets combined with the great speed that the engine reaches allows to create hypnotic patterns.
Ferromagnetism
As steel is a material that has ferromagnetic behavior, the magnetic field induced by magnets on each nail causes them to become small magnetic bars that will be oriented in the direction of the magnetic field.This process is called magnetization or magnetization.

Engine
The step -by -step engine is controlled by drivers in charge of the motor step and direction of the coils and to store the current of the same.To establish the rotation speed, we use a microcontroller that establishes the pulses so that the engine steps have a certain speed.
Industrial polishers
There is a machinery in the industry that uses a mechanism similar to this to clean large metal pieces.In jewelry a small version of these equipment with needles is used to polish and clean pieces.
