in this video clip I will assemble a device

00:00:04

called Levitron on a hall sensor, I

00:00:08

will tell you in detail how it all comes together,

00:00:11

how to assemble it and how to set it up, how it

00:00:15

works, the Levitron circuit, here it is, it

00:00:20

consists of a field-effect transistor, this is a key,

00:00:23

then an electromagnet, an electromagnet coil, a

00:00:27

diode that shunts bursts of

00:00:30

self-induction emf at turning on the

00:00:32

transistor, a resistor for the operation of the field-effect

00:00:36

transistor and a hall sensor, a

00:00:40

hall sensor it looks like this, in

00:00:44

my version it pours out like a transistor on the

00:00:49

body it says 41 and this is a case as well.

00:00:57

441 a unipolar to the case and a digital

00:01:02

output

00:01:03

this to the case and I bought it for 150

00:01:07

rubles, this is what I will use in

00:01:10

this design

00:01:11

hall sensors were different my father was looking for

00:01:14

linear

00:01:15

bipolar what kind of hall sensors and others

00:01:18

they may not work, that is,

00:01:21

there are other circuits for them

00:01:22

before the case, but it should be from

00:01:24

similar ones with similar characteristics. The

00:01:27

pinout of this hall sensor is this

00:01:30

plus the middle pin, this is the minus power supply, and

00:01:34

this pin is the limit ron output. The

00:01:40

device is called that because

00:01:43

this magnet will be in

00:01:45

still air, as if hanging, and it

00:01:48

it won’t hold any threads or

00:01:50

any pair, it won’t rely on any kind of steam, and

00:01:52

this is hovering in the air,

00:01:53

it’s called levitation, and the

00:01:56

Levitron device itself works, this thing works something

00:01:59

like this: when we apply power, the

00:02:02

electromagnet turns on and attracts the

00:02:05

magnet with its core, but between the

00:02:08

magnet and the core the magnet ector

00:02:11

is located Hall sensor

00:02:13

as soon as they sense the magnetic

00:02:15

field of the permanent magnet, it

00:02:18

bypasses this transistor, the

00:02:21

electromagnet is switched off, the magnet falls down, the

00:02:24

magnetic field weakens until the case and

00:02:27

switches to another mode, the transistor

00:02:29

opens, the electromagnet

00:02:31

is triggered at night and again begins to pull up

00:02:33

this magnet, and then everything

00:02:36

repeats itself as soon as before cover, why is the

00:02:38

magnetic field

00:02:40

the transistor switched off, the electromagnet switches

00:02:42

off

00:02:43

again, the magnet falls, then

00:02:45

is attracted again, and so the

00:02:47

attraction and repulsion

00:02:50

of this magnet constantly occurs, this happens approximately at a

00:02:53

frequency of hundreds of times per second, and we do

00:02:56

n’t see this, this oscillation exists, and in

00:02:59

the end we will see it the fact that the kabuto

00:03:03

magnet is in one place, in

00:03:04

fact, it oscillates constantly to wind the

00:03:08

electromagnet coil, I took it, but I took such a

00:03:10

tube, it is 5

00:03:14

centimeters long and the diameter in this tube is

00:03:18

about 8 millimeters, in this tube there is a

00:03:23

stalin core with such a bolt and

00:03:30

cheeks on matte coil I will use copper

00:03:37

wire with a diameter of approximately 0 4 0 5

00:03:39

millimeters

00:03:40

the coil contains approximately 450 500 turns

00:03:45

winding I start in one direction

00:03:48

to the right then electrical tape and then in the

00:03:52

same direction to the left then electrical tape

00:03:55

then again to the right and like this right

00:03:58

left right left and somewhere like this there

00:04:00

will probably be 8 layers somewhere around

00:04:05

here and I don’t put electrical

00:04:27

tape like this, the second layer ends and I move on to the third layer pierces woe and now I’ll show you how it works and how to set up the electromagnet coil, it doesn’t matter here just to be

00:04:32

sure

00:04:34

Let's say 500 turns, or you can have 470 turns, the more

00:04:38

powerful the magnet, the more current will pass through

00:04:40

it, the more current

00:04:42

will pass through it, the magnet, let's say a

00:04:46

small magnet, a bigger

00:04:49

magnet, you can attract and everything in

00:04:53

general doesn't matter, these number of

00:04:55

turns are the main diameter current will flow to it,

00:04:58

but let's say the diameter there is 0 35

00:05:01

millimeters,

00:05:04

this bolt will be inserted inside, this is

00:05:09

the core, and so this is the key, the field-effect

00:05:16

transistor, the gate resistor, the drain diode,

00:05:22

the anode, and so this is the coil,

00:05:27

two wires, and these three wires are the

00:05:30

hall sensor, that's all power supply 7 and 4

00:05:35

volts two batteries total here I

00:05:39

will set the

00:05:40

constant current measurement mode to 20 amperes

00:05:43

here is such a thing and that means it also has

00:05:47

a magnet, it’s like on one side it

00:05:52

needs to be glued to paper it will be a

00:05:54

stabilizer because if you don’t have

00:05:56

this paper you bring it to it it will start

00:05:59

jumping the brick is doomed and then it

00:06:00

will turn over and therefore there must be

00:06:02

some kind of load so that

00:06:06

this magnet will throw it down to the cover and it is

00:06:12

installed directly under this core, not

00:06:16

on the side somewhere from it, but directly below it at

00:06:19

some distance from it,

00:06:21

that is this will need to be determined

00:06:22

experimentally which side is to the cover

00:06:26

and where there are designations, that is, this

00:06:29

or that must be determined

00:06:31

experimentally because it apparently

00:06:33

all depends on the connection of the vita

00:06:35

coil to the circuit; in my version, the

00:06:40

designation inscription on the hall sensor body

00:06:43

looks directly at the core and now I

00:06:49

will fall and power

00:06:50

yum yum eat supplied current consumption

00:06:53

16 amperes and now I bring

00:06:57

this hall sensor to the core and the current

00:07:01

changes up

00:07:02

to 40 milliamps then I take it away from

00:07:08

the core further further further further further the

00:07:09

current increases with a high current

00:07:13

now and the transistor operates in linear

00:07:16

mode here 16 amperes the coil will heat up for

00:07:22

8 hours, I restored our position of the

00:07:25

hall sensor and now I take a magnet and

00:07:29

try to see that the state is

00:07:38

fixed but it wobbles a little and it’s

00:07:42

like up-down-up-down

00:07:43

this means that you need to select this is the

00:07:47

distance of the hall sensor or closer to the

00:07:50

core bolt or lower I’ll make it

00:07:52

lower now I picked it up and made this position

00:07:57

higher closer to the core the

00:08:00

hall sensor supplies power current consumption 1

00:08:04

and 5 amperes I take magnetic and now

00:08:08

we check

00:08:15

now it’s fixed

00:08:19

no sausage up and down no

00:08:22

current consumption at the same time is 420 milliamps,

00:08:26

the coil at this current will

00:08:30

heat up a little, the transistor will not heat up, and

00:08:34

now this magnet will float in the

00:08:37

air, this is called levitation,

00:08:42

if

00:08:46

you bring

00:08:48

metal into this field, then everything will be disrupted here,

00:09:16

take a little more powerful this one and the hard

00:09:18

drive, but here there is one side has

00:09:21

two poles, it needs to be broken in half so

00:09:25

that one half of this

00:09:27

magnet remains, you can also hold a larger

00:09:33

magnet, but it is unstable

00:09:45

at the same time 16 amperes, at approximately

00:10:01

this current the coil will heat up,

00:10:06

so only with a small magnet

00:10:10

inflows of 400 milliamperes

00:10:12

will the work more or less work
