The Lee-Tseung Lead Out Theory

alert :- langley recently contacted me and said the professor is on a fecal rampage for new results ... this cant be good

Now I can start with the juicy discussions on Experiment001.

Before we go into the theoretical discussions, we can focus on the experimental results.

It is shown in the following diagram.

The movement is towards the unpadded surface.  In our case, it is towards the elastic collision surface.  (More on that later.)

To be continued.

Let me now discuss Experiment001 in separate stages.

The first stage is that both permanent magnets received the same magnetic repulsion and will fly off in opposite direction.  The net momentum of the device must be zero.

Tinselkoala failed to set up this part.  His magnets stuck together.  The probable reason is that his electromagnet is not strong enough or his permanent magnets were too strong and placed too close to the soft iron core.

In this first stage friction between the device and table plays no part.  The two magnets happily go on their opposite paths with the same velocity and momentum.

The net momentum of the device is still equal to 0.

In the next part, we need to introduce the concept of elastic and inelastic collisions.

In Physics, eleastic collision refers to the situation where there is no loss of kinetic energy - nothing is converted into heat or sound.  The object and the wall will not deform.  The solid surface is an approximation.  On hitting the surface, the velocity is reversed.  There is a change of momentum of the magnet from mv to -mv or (mv-(-mv)).  The value is thus 2mv.  The force F1 is given by the rate of change of momentum.  The value is 2mv/t1.  t1 is made to be as short as possible so that F1 is as large as possible.

This part can be considered alone.  Thus F1 can be determined.

In Physics, inelastic collision refers to the situation where there is loss of kinetic energy - much of it is converted into heat, sound or deformation.  The padded surface is an approximation.  On hitting the padded surface, the velocity is also reverse but its value will be much less (v1).  The value is (mv -(-mv1) or m(v+v1).  Since v1 is less than v, the change in momentum is less than 2 mv.  This value is less than the solid surface case.  The force F2 is the rate of change of momentum.  The valude is m(v+v1)/t2.  t2 is made to be as long as possible so that F2 is as small as possible.

The trick is to have the largest difference between F1 and F2.  This is the design principle.  The Bull and Naudin devices did not follow the above design principle and are thus useless devices.

@ TopGun:

I am sorry to see that you still do not get it.  You are missing a fundamental part of all this.  Go ahead and suspend this in the air so it is free swinging and see what happens.  You won't because you already know.  Everyone already knows.  As I said before, unless you are planning to take the table with you into space, this will not work as a propulsion device.  I really wish it would, but, it won't.

Respectfully,
