Thursday May 30th, 2013 14:50 “Antigravity” method 10b of 15 Electromagnetic suspension with feedback Group IIIA

Filmed 1991-1996, 10b of 15 methods of levitating an object known to the author John Iwaszko, edited from the video Antigravity the reality made in 1996. The antigravity method shown in this edit, at the time was classified as Method 10 of 15, Electromagnetic Suspension-repulsion or attraction with feedback loop control, Group IIIA. It is well known that the attraction from a permanent magnet decreases with increased distance, and increases at closer distances, which is ‘unstable’, unless tethered or pivoted or rotated such as shown in methods 5, 6 and 9. It is also possible to create a stable system by using the opposite principle by varying the magnetic field of a permanent magnet or a dc powered electromagnet that will push a permanent magnet back to a stable position. Stable magnetic levitation can be achieved by electronic control circuitry that can measure the position and speed of the object being levitated, and using some type of feedback system which continuously adjusts one or more electromagnets to correct the object’s motion, thus forming a servomechanism, and although a direct current supplies the electromagnet the power, the electromagnet oscillates between off and on state and also switch between polarity so has been grouped with alternating AC current levitation, also called Electromagnetic suspension (EMS), and is successfully controlled by a correct position of the sensor or sensors utilised as well, as exact current control such as driving the

      thanks for clearing a few things up for me,im working on antigravity myself ,soon i hope to shhow you something interesting, i hope:)

      I deeply wish to buy this film. Do you know where I can get it?

      @1awareness, thanks for your interest, the series is not complete, I need time to re-edit as I am in the process of editing the footage from the original super 8 filmed from 1991 onward, rather than the poor quality VHS copy that the YouTube vids were downloaded from.
      Also I have many new experiments that I wish to add.
      Will let you know when available
      Thanks JRI

      Very interesting, but it would be better if the music were gone and the voice was edited to be more audible (i.e. louder)

      @starfire714 Thanks for your comment, I agree, what may also help is watching the presentation on a better high fidelity system, also check the balance control on your speaker.
      Cheers

      This a fabulous video!
      However, the scientific and entertainment values would be greatly enhanced if the music was removed. Your voice is all that is needed here. The background music only distracts the viewer from the facts you are so eloquently describing.
      Thank you.
