The Lee-Tseung Lead Out Theory

What's the matter? Scared?
Meanwhile, genuine science progresses in leaps and bounds.

Some early results of Experiments:

The following set up was used:
(1) A HK$25 Cylindrical Magnet
(2) A 12 Volt power supply
(3) 20 turns of Number 18 copper wire
(4) Transparent tube of 130 mm length

The results are:
(1) Use repulsion - jumped 120 mm approx.
(20 Use attraction - jumped 180 mm approx (the youtube video)

That's pretty feeble!

Especially since my entire apparatus shown in the two videos I posted above, cost less than your single magnet.
And it works much better!


(By the way, you will soon injure yourself with that big magnet if you casually fling it around like that. You can put an eye out, or smash a finger severely. Is it worth it, just to invent the solenoid?)

The attached picture showed the Dr. Raymond Ting improvement.  The coil attracts the magnet to move rapidly upwards,  As soon as the magnet reaches the middle of the coil, the upward momentum (force) is changed to a downward force.  The upward momentum carries the entire tube upwards.

From momentum consideration:   M1 * V1 = (M1+M2) * V2 and
From energy consideration:          (M1 * V1*V1)/2 = ((M1+M2)*V2*V2)/2

The resulting jump height is greater than 180mm.

I think TK put it best.  You have invented jumping!  Congratulations.
