Ok lets try this again
In no particular order
The waves involved are mainly 4 types (someone correct me if I forget any)
1) Magnetic waves, yes let call them waves seeing as we have decided real names dont matter. For those that like science these waves are actually Magnetic fields, they only become waves in certain sci fi machines. These come from the various magnets in the circuit, while we are pretending only one magnet exists, actually the motor has some as well. But lets not get hung up on technically stuff, this is meant to be educational not informational!!!
2) Electro magnetic waves, again dont call them fields unless you want to use correct terms!! These can be ignored for educational purposes. But if you just want to know something and not learn anything, then you may call them
Electro
Magnetic
Fields. Which depending which wiki page you read (if your allowed to read), is what EMF stands for, although I have also seen it stand for Electro Magnetic Force....
3) Radio waves... These will be coming from different aspects, for a start the commutator on the motor sparks, the first radio used sparks to generate Radio waves. Yes they are actually waves. I havnt looked at them closely with the Spectrum analyzer yet. So I dont know what frequencies are involved. But as the motor is inductive and dosnt have any suppression, it would be reasonable to assume some high frequency stuff in the mix.
Is It Dangerous?
Yes and
NO. Its mainly dangerous because alot of this is being twisted into something it isnt. But on the other hand anyone with sense will have read the links so most will be safe.
Is It Harmful? No, not at all with the power levels involved. We are dealing with extremely small amounts of power. Yes 200V+ sounds alot, but power (as in coulombs and joules etc), are very very low. If your not doing this for educational purposes then you can work the power out. The formulae is simply Volts Multiplied by the Amps. In this case dont forget that
1mA is NOT 0.1A!!
A mA is actually 0.001A, so when you see figures like 200V it sounds alot. But the motor itself is only using
5.1 V @ ~ 480mA (I think that was the figure given). So on the motor side this would be
5.1 X 0.480 = 2.448W So would you be frighted of a small motor hurting you? if you look at the coil side then its even lower..
We know the voltage is
200V we know the meter shows
0.00A, So from this we can confer that the coil produces under
9mA if it produced over that then the meter would read
0.01A.
Keep in mind you can light a led with ANY voltage above its Vf (forward Voltage) Most leds are between 2.2V-~3.7V. Most leds will light and be easy to see at 1mA, I have dev kits with smd leds that pull uA!!!. But lets be generous and say the coil produces 1mA.
So you have
200 X 0.001A = 0.2W
So compare the two, the motor uses
2.448W of power to produce
0.2W of power. Extra marks for anyone smart enough to spot the problem here. Incase you cant I will spell it out.
Lets say I offer you a job, the deal is you pay me £2.44 per hour to work for me, in return for your work I will pay you £0.20 per hour. Sound fair? Apply by pm please.
HOWEVER lets not forget this educational, so facts dont matter. Lets concentrate on what we
THINK we Know. We think because the bulb has 7W on it, then it will only work at 7W. We will ignore that the fact that leds are actually Diodes that emit light, we will forget that Leds are a
CURRENT device.
So now we do our calcs based on the wrong assumptions we have made, so we assume that we have produced
7W.
Now this is a real problem, because you have to decide something at this point. Do you believe in
SCIENCE FACT or do you believe in
SCIENCE FICTION?
Here is the problem you face if assume
200V @ 7W. Because that would mean the coil had produced
35mA, Obviously if that had happened the meter would have read
0.03A But it didnt.
So lets look at the more likely figures. @1mA the coil would produce
200V X 0.001 = 0.2W. Now these figures dont seem too bad. Until you work out that use
12.24 X the power than you produce. Dosnt sound much but try and scale that up!!
Even best case scenario would be
200V X 0.009A = 1.8W
Still using more than it makes. But using real numbers with meters that can read uA, you find out that
1.8W Is a dream and not reality. This is why we have no results from the OP regarding trying a bulb or motor
. simply because there is not enough power produced to light anything other than a very low current device
.
But its all educational so facts dont matter, instead we focus on the 200V and clap ourselves on the back. We also ignore that 200V from a magnet,motor,coil and 5.1V power source, is pretty pee poor compared to around 5000V produced in one the videos using just dripping water! Or 25 X more Voltage from dripping water than the current set up that uses a battery!. But still the OP wonders why no one is wetting themselves with awe and wonder.....
