A CRY FOR HELP

I have two more pages of posts to catch up on so I will read them after posting this.

Right oh, I need a bit of help from the gurus who know about torids, weather a forum member or not.
I posted several pages back I need to see a video of what occurs inside a torid when it is working, I want to understand how this thing operates.

Can anyone reading this point me to the web address that explains it, in a simple way?

Hi Jim,

I like this site.

http://hyperphysics.phy-astr.gsu.edu/Hbase/magnetic/toroid.html

That is the toroid page.

The math is complicated, but then, it is.

But the pictures are so clear, you can see what the drawing means. And, you can also see why this is so powerful.

@All,

I am afraid I have seen no warmth with the IR leds. I did some research and I guess, I probably was thinking about IR from a too[hopeful point of view!  Oh darn.

I yelled out for HELP and got a avalanch of it ha ha

@ Xee2 and MK1 and TheNOP,
Thankyou for your kind help with sending me https links and presenting other bits and pieces relating to Induction.

A lot of it I carnt make any thing out of, but sofar I learnt if the Right Hand RULE for Solonoids

Hold a coil in ones right hand, the thumb pointing out to the right, palm open.
Imagine you are holding a coil, now curl your fingers up and over the coil.

Next imagine drawing a magnet out of the coil with your left hand.

The electric push goes to the right whilst the magnet is pulled out the left.

I assume the opersate takes place when inserting the magnet.

NOW, I think the JT is making the same thing happen in the torrid  <---> but at high speed.

Is this the FLUX going backwards and forwards? hmmmm and EDDIE currents are those that follow the fingers direction and they reverse also? hmmmmm

I would love to see a video of this happenning, a picture tells a thousand words, and just creates more questions to answer. lol

Thanks again fellas.

My big torid is

Diameter = 103mm
Width     =   30mm
Hight      =   31mm

Colour    =   Grey     which means it is configured for low Hz not Yellow/White for 150kHz or higher.

Well as we seem to be breaking all the known rules in this forum, who cares, lets break another one lol
I'll wind it and see what happens.
