hi why why is internet filled with fake
garbage like this guy making a fake
generator to charge a cellphone he glues
two magnets to a motor shaft solder the
wall adapter to his motor makes a copper
coil and solder x' a five volt voltage
regulator to it as well as a cell phone
USB connector plugs them into the cell
phone and turns the motor on and
apparently the rotating magnet generates
enough electricity to charge the phone
he's not alone though there is a whole
army of idiots out there like this one
who claims putting broken china in milk
for two days mens it completely together
this video got over 144 million views on
facebook my entire channel has 88
million you know one of my relatives
fell for it and tried it just to be left
with the same broken pieces now smelling
like a rotten cow videos like these
wastes everyone times and resources
because now everyone wants to try them
obviously milk doesn't man china all
they did was to replace the broken plate
with a good one and they tried to match
the location of the red tapes see in the
same video they had a bunch of other
tips that could actually work and then
they leave this fake garbage in there
too making fake news is an art one of my
friends once told me that the best lie
is the one that's wrapped in truth a
bunch of good tips makes everyone
believe in the one horrible fake one now
please don't take this wisdom and starts
making things so that's what the milk
guy did why i mean i know why you're
looking for the juicy YouTube money and
views but you have to be at a certain
level of evil to be willing to waste
time and resources in such a great scale
have you seen few Joe's videos he has an
entire channel dedicated to fake
technology with more than one and a half
million subscribers like how to double
your internet speed or charge your phone
in no time all by wrapping aluminum foil
and a bunch of wires around its gonna
let you recharge your phone almost
instantly you're obviously going to need
your phone normal charging cable tin
foil some sort of wire you just want to
take your phone and just wrap
Kord around get your tinfoil and just
wrap this around your phone we're gonna
plug this in for about 10 seconds 70% is
pretty good for going from 1% up to 78
at least now he mentions his videos are
fake and joke in the video description
so less evil maybe but whoever reads the
video description first before trying
such people waste time of people like me
to have to debunkers except that every
time I make a debug video I also get the
juicy YouTube one but that's not the
point
anyways let's get back to the fake phone
charger it looks like a generator but
it's not now you might say this guy
looks like a decent guy who made a good
generator I mean why should you trust me
if you almost kill myself in every video
everyone knows moving a magnet beside a
coil generates electricity and he even
tried to use a 5 volt regulator to have
a proper charging voltage unlike me who
killed my phone trying to make a
hand-cranked charger with no regulator
just shut up there are a million reasons
why this is failing well first it
doesn't matter if you have a 5 volt wall
adapter you can just directly plug it to
your phone and charge it why turn and
generate or way they to charge the phone
but that's not the point let me tell you
how it generator works if you have
magnetic fields like this and a wire
moves and cuts them perpendicular to the
magnetic fields then the electricity is
generated in the wire but if the wire is
not perpendicular to the fields only the
field vector that is perpendicular to
the wire makes electricity in the wire
so if your wire is moving parallel to
the fields it doesn't create electricity
at all the way the guy has it set up if
we have the coil like this and look at
the magnet from the bottom then the
fields would be coming out like this so
if we rotate the mind that you're right
get out
we need a 3d representation
of the magnet here is my paper magnet
and the paper magnetic fields going from
one pole to the other and this is my
coil now if I insert the magnet into the
coil like this you see that the coil
will have to cut through the magnetic
fields and that creates electricity but
if I rotate the magnet like this Center
to the coil you see that the coil
doesn't necessarily cut any magnetic
fields so no electricity if you rotate
the magnet 90 degrees and insert it into
the coil you see the coil into
magnetic fields but it's pretty useless
because it is cutting into opposing
magnetic fields so the magnetic fields
push electrons this way on one side and
the other way on the other side and they
cancel each other also if you turn the
magnet like this it's pretty useless
because the coil doesn't cut into any
magnetic fields so using these you see
that the guy has set up his magnet the
worse way that creates the least
electricity if any the actual generators
have their magnet set up like this into
the coil and they turn this way let me
show you the actual electricity
generated in a coil on my scope which I
love and cherish of your way three of
these at the end of my video I have a
bunch of magnets that are polarized like
this north on one side and south on the
other side so if I stacked them together
like this it'll give me a big magnet if
I want an over the north of the magnet
is I just put it on a string and let go
and it turns towards the north which is
in that direction behind me now if I
shove the magnet into the coil I see
that the voltage is generated and the
faster I go the higher the amplitude
like this what are we doing what just
closed the door next time now let's make
the same setup as the guy in the video I
put my two magnets on a nail like this
and will rotate it with my drill now if
I turn the magnet Center to the coil I
only get tiny fluctuations because my
magnet or coil are not curved
but if I shift it to one side
I'll get higher voltages and in the best
case if I turn it like this
I'll get the maximum voltage and that's
how the generators work the other reason
he's generator is a piece of is that
something like this doesn't generate any
significant voltage the best I was able
to capture was around 60 millivolts you
need many more number of turns and a
very good inductor core to capture most
of the energy the other reason is that
as you saw on the scope such a generator
outputs an AC voltage you need a full
bridge rectifier first to convert it
into DC before converting it into five
volt using the regulator use you can get
your full bridge rectifier from the link
below it's not gonna rectify anything
though it's just a shared not only we
need to rectify AC into DC first we need
a DC level more than five volts to be
able to use the linear regulator he
using his video and all we got was
around 60 millivolt peak I assure you
his generator is a garbage but wait
another nail in the coffin this is the
hand cranked phone charger I made in my
other video it has an actual generator
that outputs to a rectifier circuit the
DC generated goes to a 5 volt switching
regulator that outputs to a USB port for
charging the phone it turns freely like
this what as soon as I plug it in to
charge the phone it is much harder to
turn because it's taking power from me
to charge the phone somewhere around 3
watts of power what his motor doesn't
slow down a bit under the charging load
when he brings the coil close
[Music]
and finally the last nail in his coffin
fine let's assume he's making enough
electricity and he's taking current from
the coil charging the phone that current
through the coil makes its own magnetic
fields that interferes with the rotating
magnets see like this I'm running some
current through the coil and when I
bring the magnet close it jumps around
like this but his coil is not moving at
all
all I'm saying is that he made a fake
phone charger and now a word from the
makers of the world's most expensive
cell phone chargers keysight we at
keysight like to charge our phones in
style some of us like to use the four
and $50 cell phone charger but I like to
use the $450,000 at KGB grade natural
Mama's cell phone charger definitely
some sort of us now wait I always want
the climatescope since I was a baby to
see exactly what's continuously coming
off this thing teaches you electronics
that's why I'd like to give you three
more of these fantastic high side scopes
it's more than just any scope it has a
20 megahertz function generator or a
frequency counter and much more this
time one goes to you the viewers and the
other two go to my patrons at
patreon.com which you could be one tune
for the viewers I know an oscilloscope
is not for everyone so if you really
like it you have to enter the draw by
subscribing to keysight oscilloscopes
channel and also leave a comment under
my video saying that you wanted
something like give me that key site I
know I'm not very creative either do
your best and good luck for more
practical oscilloscope tips and less
bushy eyebrow again come join me on the
key seta so Scott YouTube channel
