Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

I hope this shows up correctly.  All three are magnetic.  I tied a string to only one and it lifted the other two.  I doubt the little one would lift the two big ones, but it is still magnetic on its own.  Why would they be magnetic and does anyone know what they are?  I call the two big ones caps because on the board the first letter was a C.

I'm just throwing this out because one looks like my variable inductor I bought from Digikey.  The numbers and letters don't match but they could be manufacturer specific.
Is there a slot on top that you could use a screw driver with to turn the inside?  This is how my variable inductor works anyways.

Hi protonmom,
The little one with the copper wire exposed is an inductor.

(In some of my posts I have been saying,  "I added a 220uH inductor".  It looks exactly like that.)

It must be a magnet because it was magnetized by being used?, but I didn't think ferrite kept the magnetization.
Maybe the other 2 are also, but I do not know about them.

You could put the copper one in series with a pulsing circuit and see if it enhances it.
That could happen if it is the right size. And since computers or tvs are in high frequency levels it might be.

Then you will want a meter so you can know what it is!
Ah, it never ends, does it?
But get the scope first!

I believe they are all inductors, one variable and two fixed. Being obviously magnetic, now that's interesting. Nice pic's by the way, now I understand what you are talking about.

My best guess, these are iron core inductors which could retain a magnetic polarity. I think iron cores are used typically in low frequency applications, but don't quote me on that.

I thought they would have lost their magnetism by now, but they are all three still going strong.  Now on the large ones there is a neg and pos side.  On one I found a number of(160) only the zero looks like it has a slash line through it.  The other one has the number125 (degrees)  (I don't know how to put the degree mark in here) And then there is a V and the rest is covered with that former label of 2031 LAE.  Actually that "V" might be a "W"  since it is covered I cannot tell.  Just past the label there is what appears to be a minus sign.
There are NO screw slots for adjustment on any of the three.  The material on the little one which Jeanna says is an inductor looks to be plastic, but the material inside the large ones almost looks like ferrite.  There is a very large negative push when you put the two side by side.  Wonder how that might be useful to me.
