TinselKoala's Magnetics Workbench

[0c]

I'll try to set up the experiment exactly as you describe, only different, as usual.

I tried to give you enough rope to do things your way. Thanks. 

Meanwhile you may (or may not) be interested in this new video, where I used the TBC as a primary in a Tesla power magnifying system in a replication (partial) of gotoluc's and groundloop's work.

Could you provide some references for us ignorant sods that don't know much about gotoluc or groundloop? Just what is the significance of the experiment?

As I feared, all the arcs, sparks, and bright lights have got TK hypnotized. All good fun, but it hasn't answered any of the magnetics questions I posed.

Sigh.

Yes, you won't believe what I scored yesterday at Active Surplus. For some reason, they have a bunch of brand new bright and shiny Taiwanese-made hubcaps of the "baby moon" variety. For a buck and a half each!! These are incredible, shiny, smooth, no detail markings. Two together make an ideal capacitative top-load for high-voltage work. I plan to use several of them making table-top Van De Graaff machines to add to my electrostatic zoo. Meanwhile I have taped 2 together to make a beautiful flying saucer-shaped topload for my current (pun intended) set of experiments.

@0c: I guess that, since I'm paying my own salary, I get to choose what I work on, and when. Let's see: So far, in seeking to answer your questions, I have constructed 3 unique coils and pressed a 4th one into service; I have constructed and begun to characterize an appropriate driver/pulser module that is capable of driving what is essentially a dead short, to RMS voltages in excess of 100 V; I've spent time shopping and thinking and studying; and some other stuff like that there. If you want to get sarcastic about any "lack of progress" that you might perceive, perhaps I can go and find something else to work on for a while, while you re-evaluate your attitude toward what I am (or am not) doing.

TK,

I, for one, am enjoying the hell out of what you have shown so far.  Really interesting, IMHO.

It's always possible to get back to the question from which you strayed.  But how much "science" would have been missed if one didn't investigate every unexpected phenomenon one discovers along the way?

Thanks for sharing in such an informative way.

I just became aware of a recent and closely related demonstration on youtube:

There are a number of differences. I like ZEROPOINT132's approach to spinning a magnet. It's simple and elegant. But it has a problem as well.

The poles tend to orient up and down (watch when he adds the paperclip) instead of towards the coil. My approach had a freely spinning diametrically magnetized magnet mounted on the end of a pendulum and oriented so the poles would spin directly facing the coil, which should produce a spinning field with more oomph per pass.

The experiment in the video uses 2 coils and a reed switch. My experiment uses a Tesla Bifilar Coil. I never considered using 2 coils or a switch. I was mostly thinking about the interaction of the fields WRT the coil and the magnetic behavior of a Tesla Bifilar Coil.

ZEROPOINT132 goes a step further and uses a simple LED to demonstrate the current generation, instead of using a scope to see it. I didn't realize it might generate enough juice to light an LED.

Hats off to ZEROPOINT132!

(TK, you could have been there first.)
