After that very helpful posting if I see one more jackass try to tell me what a horrible person I am, then they can shut their mouths and kiss my ass.
Thanks for your post and effort MH. I know all too well that most either can't or choose not to appreciate the effort that goes into posts which aim to explain and educate.

What this forum needs is more civilized posts and discussions, rather than the tirades this thread is being flooded with lately.

Again, the only core material I have ever seen increase Inductance by a magnet (without need of movement) is Finemet.
I suggest you get some toroids and test it out like I did in my demo video.

You can buy them here: http://www.elnamagnetics.com/catalogs 
If you have some kind of business you may be able to request a free sample.

I've attached some PDF's

It is interesting that in the Finemet document all the "Inductance vs. DC Bias Current" graphs show the inductance deceasing as the DC bias is increased. That seems contrary to your results Luc.

Which core model did you demo in your video?

Unfortunately I didn't bring the Finemet toroid with me and won't be going back to Ottawa until mid April.

I remember getting the part number from the Orbo topic in 2010 or 2011. I don't know if you can do a key word "Finemet" search in a specific topic?

Let me know if you do find the part number and I'll order a new one to test as well.

Thanks

Luc

My search for your posts did not pull up any part numbers. Suppose we need to find the orbo topics.

A Google search of "orbo" and "core" was not fruitful for me either.

Luc,

Did you perhaps use the same part number/core mentioned in this video that you linked to in a post you made discussing this? (Part number MP1305LF3T)

I forgot I started a topic about it. Thanks PW for finding it.

Eric is the one who first brought my attention to this Inductance boost by magnet. However,  I already had the 2 Finemet Toroid for Orbo testing but good chances they may be the same, they look to be about the same size. One way or the other we know his part number works, so I would say that should be good enough.

Eric's test setup is not very refined but proved the point. After my tests I found the ideal magnet size and magnet location to maximize Inductance which was in the toroid center.
Magnet was 1/4 inch N45 Neo cylinder, magnetized top to bottom.

Hope this helps

Luc

I just found this topic as well

http://overunity.com/8892/self-running-coil/msg236731/#msg236731

Looks like Eric is user void109 and had a MP1305LF3T finemet toroid. So he is the one who brought my attention to it in April 2010.
I refined the effect to minimum magnet size and ideal magnet location (toroid center) to maximize Inductance.

The field is always there.
It can be negative or positive
It can be captured in both signs.
Use it.

Hey guy's

just letting you know that i will more than likely be off line for some time.
The south west of our state (where i live) is being devastated by the largest recorded bush fire so far.
The fire has already taken out 1 town,and half of another on it's way toward my area.
Power in some areas has been lost,and it seems that most of the south west is going to loose power for some weeks due to the fires. There is no more fuel available from the service stations,as our corner has been cut off due to both the major highways being closed. Food is also going to be an issue ,due to the fact that no truck can get to this corner of the state ATM.

So were just going to dig in for the long haul,and will be back as soon as everything returns back to normal around here.

Good grief Brad.  Not good news at all.

Hang in there best you can and know your limitations.  When it's time to go, make sure you have time to go.  Get everything packed up sooner rather than later.

I'll keep my fingers crossed for you, hoping this blaze turns itself off.

Wow Brad, that's serious stuff, take care, and like Dog said;  "When it's time to go, make sure you have time to go"

Take care Brad.

Hope all goes well and we see you back soon.

What area are you in?

Take care Brad.

Hope all goes well and we see you back soon.

What area are you in?

I am in the Bunbury area. The next suburb along is Eaton/Australind.=-They are on an alert and act warning ATM. Standing at my front door,i can see the orange glow from the fire. Over 7000 hectare's and one town have been destroyed so far,and the fire has just hit the second town along in it's path(Harvey)

For the moment,Eaton,Australind,and Bunbury are safe,and we are hoping for rain tonight/tomorrow. Lets hope the weather man get's it right this time. Only problem being,it was the summer thunder storms we get this time of year,that started the fire to begin with. The other problem is that the fire is so large and hot,that it now has produced it's own weather pattern,and lightning can be seen coming from the smoke clouds.

The most north/western suburbs of Bunbury have reported red hot embers landing in peoples yard's,and a couple of small spot fires have been dealt with. The biggest problem is no vehicles can get in or out of the south west corner,as both major highways are now closed due to burnt and collapsed bridges. Fuel/gasoline has run dry already at most service station's,and it seems as there may also be a food shortage soon--so now every one is doing the !!mad pannic shoppers!! dash-which only makes things worse.

Anyway,i will keep you all updated as i can


Brad.

Well it is good that you have the ocean and all that sand close by !
Scary stuff indeed ...

Be safe ...will keep you and yours in our thoughts and prayers !
