In this article, Konstantin, How-todo workshop, will show us how to make a Levitron.
So, Levitron. The principle of operation of this stray is simple, like a self-tapping screw. By electromagnet we lift into the air a piece of a certain magnetic material. To create the effect of soaring, we turn the electromagnet on and off with a high frequency.
That is, as it were, we raise and throw the magnetic sample.
The circuit of such a device is surprisingly simple, and it is not difficult to repeat it. Here is the actual diagram.
The materials and components we need.
LED of any color, it is optional.
The IRFZ44N transistor is suitable for almost any field-like device with similar parameters.
Diode, here the author uses HER207, with the same success some 1N4007 will work.
Resistors at 1 kΩ and 330 Ω (the latter is optional).
Hall sensor, I have it A3144 it can also be replaced by a similar one.
Copper winding enameled wire with a diameter of 0.3 to 0.4 mm, meters 20. The author has a wire of 0.36 mm.
A neodymium magnet like a tablet, measuring 5 by 1 mm, is also not very important, within reason.
An unnecessary five-volt charger from the phone is suitable as a power source.
Glue, paper, soldering iron solder ... a standard set of soldering iron.
By the way, a list of all components with links to
