I was somewhere reading that every electron has a spin and a north and a South Pole and "when first electrons are caused to flow in a wire" the adjustment of this poles or spin is changing and this gives the kick.


They call it Spintronic!

Actually both electrons, and protons do this, and it's called precession, and its the basis of how magnetometers, and metal detectors work.

Proton and electron precession are factors used in "spintronics", but in and of itself is not spintronics as a whole.

It also causes a burst of energy that induces eddy currents in metals. With metal detectors the idea is to "mask out" the earth's magnetic field in order detect these eddy currents..

Now what kind of energy causes eddy currents in metals even through several feet of dirt?


@EMDevices... Nice post.

Hi EM Devices,

Very good observation on resonance, I posted about tunning forks, I suggest for people here to get one, because when they are hit in the hand they resonate quite for along time, now if a rotational magnetic field does not produce a gyroscopic effect as what happens with SM devices, its this component that would make that happen.

The large number of small kicks would to me be this resonant frequency, hence when a current in a wire or vacuum tube is first turned on, it reacts with the earths magnetic field , So in effect the earths magnetic field is the resonant frequency we are picking up.

This is a very good point and one that must not be forgotten.

Again, I say this time and time again, keep it simple, nature is simple and not complex.

Sincerely,

Dom

Sam, your joking right? You can't be serious.. Are you seriously encouraging people to "experiment" with shocking themselves with high voltage for "experience" sake?

Why don't we all just shoot ourselves in the legs with various calibur guns to study ballistics?

Do you think we don't know what would happen? Sounds to me like you've had a few too many of these jolts.

I'm up for the hand-cranked alternator attached to both knees for self inflicted fun.
Woo-hoo!

giantkiller,

you must be about my age.  dad used to have one the old wind up telephones in his shop when we were kids.  we used to love to play with that thing.

if you really want to feel some current if you still have a push mower around, grab a sparkplug wire, (while it is not running) and pull the cord very slowly. if you do it right you shouldn't feel more than one jolt from the capasitor.  DO NOT LET ANYONE ELSE PULL THE WINDER FOR THIS ONE!!!!!  TRUST ME MY LITTLE BROTHER DID THAT ONCE AND I LIT HIM UP!

lol
sam

ps:they say my granddad could ground out an eight cylinder car.
by grabbing a sparkplug wire and then somebody. how can that work




Resistance. Ten people can hold hands and grab 120vac. Don't do 240! It can jump to ground!
Also it is the salt on your skin that conducts in water, not the water.

Guys, So I replace the mosfet with a relay.  We have a relay a wire and a resistor, nothing more.  Still this kick is seen.  Can anyone say what can cause inrush here?  Temperature change of relay contacts or the resistor makes an increase in the resistance and drops the current?  It is low power here, no heat.

Can anyone suggest how to make it even more fool proof, ie illiminate any remaining normal inrush current factors?  If we still then see it after all causing factors are removed, then it has another cause.  I need a 100% test.

We can see the signal spike at the instant the current flows, then it drops below the steady level, then a small spike, then it levels out.  This drop below can be the relay contact bouncing apart just after they close.

Still it does not feel right.  The electrons have still be taken from the battery and go to the positive side.  This kick will just help to drain the battery quicker!


Dave.

You want to isolate it from the PSU right? Have you tried a spark gap? Discharge a cap at about 20kv through a sparkplug. No power coming from the psu before or after the discharge. That should give you a clean reading of only the point when "a current is first caused to flow" in the wire.
