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 ...
