TinselKoala's Magnetics Workbench

Here's a link to TinselKoala's very informative Youtube videos. It's a good place to start learning some interesting physics.

... and here's some more of TK's stuff:

The electrolysis videos in the mess at mediafire are to be considered preliminary. I will be doing a little more in that line after the holidays.

Meanwhile, today I made 2 small comparison coils in an effort to get ready to answer some of 0c's questions. I'll post a picture of them in a few minutes. One is a standard pancake coil and the other is a series Tesla bifilar, as illustrated in 512340. They both use exactly the same amount of wire.

Tomorrow I will hook these coils up to some very expensive test equipment and try to determine their inductances, distributed capacitances, and so forth.

Later, I may be able to compare the performance of these coils as primaries for a little VHF TC.

I would be glad to hear of some easy experiments and tests to try with these coils.

I would not expect the DC or LF magnetic fields produced by the coils to differ. There may be some differences at higher frequencies, especially the autoresonances. The capacitances will definitely differ...the bifilar will store more charge...hmmm.
Hmmm.

Nice work TK,

Those coils look great. There might be a minor issue though if we want to flip them upside down. Since I am primarily focussed on the magnetic characteristics, we may want to have access to one or the other magnetic pole, or maybe even both. And I was considering a pendulum above the coil, so different coil heights might be an issue. Maybe some legs instead of lrf's might do the trick.

This will work fine for initial investigations though, checking the magnetic (and electrical) characteristics. Depending on what we learn here, some of things I am considerin may not be needed.

Thanks,
