Dave45:

Then why don't you open up a thread and explain how it works and show some free energy experiments, explain the freezing water business, the whole nine yards?  But my request is absolutely refrain from hints and teases and smoke and mirrors.  Just be straight and put forth your proposition.

The coils Iv shown create a spinning aether vortex and yes I have seen this in my ice experiments.......... :-\
never mind its usless  :-\

Hey Dave

Have you done the freeze test on a normal coil in the water?

I am going to try a simple example to demystify Ampere's Law and then relate it back to the toroid.  No math, just a thought experiment instead.

<<< Ampère's circuital law, discovered by André-Marie Ampère in 1826,[1] relates the integrated magnetic field around a closed loop to the electric current passing through the loop. >>>

Let's suppose you are in a room and in the center of the room there is a vertical conductor that goes from the floor to the ceiling with one ampere through it.   The current is flowing upwards.

You face the conductor and you know that you are standing in a magnetic field.  From the right hand rule you know that the magnetic field is pointing to the right.  It has a certain strength, let's call it B1.

You have a task to do.  The task is to record the magnetic field strength times the distance you have to walk around the circle of the magnetic field.  No need to ask why, you just do the task.

Now, facing the conductor all the time, you move one meter to the right.  We will say your distance from the wire is R1.  On a pad you record B1 x 1 meter.  You keep doing that and adding up the steps.  Let's suppose you move 10 meters total to make the full circle.  You end up with B1 x 10 meters.

Lets say you move closer to the wire.  We will say your distance to the wire is now R2.  Now the magnetic field strength has increased to B2.  To make the full circle this time you move only 5 meters.   So you end up with B2 x 5 meters.

In both cases you have gone full-circle and you have two summations.  Think about this:  The closer you are, the stronger the magnetic field.  And also, the closer you are the smaller distance to make the circle.   So it would seem to make sense that B1 x 10 meters should be equivalent to B2 x 5 meters.

What are the units for a magnetic field?  From Ampere's law we know that B1 x 10 meters = the current in the wire.  Think about the fact that the wire is the actual source of the magnetic field.

We can say that B x meters = Current (From Ampere's Law).   That means that B is simply equal to current/meters.   And that is indeed the case, you can express the magnetic field in the units of amperes per meter.

When you walk around the circle you you add up magnetic field in amperes per meter times the meters you walk -> that gives you amperes.

Now, suppose that there is a second wire 50 centimeters away from the first wire.  It also has one ampere of current flowing through it going upwards.   Now the magnetic field will not be the same strength in every place as you walk around the circle.  However, when you do your summation you will end up with the B x meters walked giving you a result of two amperes.  The B changes as you move but that's doesn't matter.  You end up with two amperes in the loop that you formed by walking around the two wires.

Now here is a key point.  Let's make the current in the second wire go downwards instead of upwards.   Recall that the original wire has current going from bottom to top.

As you walk around the loop and take note of the magnetic field strength it varies.  In fact when you are closer to the original wire the magnetic field is going to the right.  However, now when you are closer to the new wire with the downward current flow, the magnetic field is going to the left.  You should be able to see that part of your loop will have a "positive" field x distance summation and part of the loop will have a "negative" field times distance summation.  Therefore when you travel through the complete 360-degree loop, the summation will be "positive field x distance" plus "negative field x distance" for a net result of the distance x field summation being zero amperes.   Since one wire has one ampere of current gong from bottom to top and the other wire has one ampere of current going from top to bottom the net current going through the "walk around" loop is zero.  So it all works out, net zero amperes current flow equals net zero field times distance.

Very important point:   Even though the summation is zero, the magnetic field is not necessarily zero in this two-wire example as you walk around the loop.

Next posting for the big reveal.

@MH
I for one,will be looking forward to that next posting,as the first make's complete sence.
So with that being said,im about to throw a spanner in the work's with something i am building at the moment.I will try and get the video done and up by tonight-here on this thread.It's not so much a device to try and gain energy,but more a tool for learning.
