"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 electromagnet with a pulse width modulated signal. The repeating pulse changes its width to apply the correct power to the device over time.
There are many methods that can be used to achieve EMS, such as magnetic field coils close to a levitated magnet. The crowning glory of this opus is the magical and remarkable levitating 240V 25W BC incandescent GLS lamp, illuminated wirelessly by the high frequency field from the Electrical transmitter seen on the right, a receiving coil is looped around the lamp, receives the energy wirelessly through space and is illuminated. I could have been more environmentally friendly and illuminated four compact fluorescent lamps of 10 Watts each, but there is nothing more beautiful, the glow of an incandescent lamp. This combines my three scientific passions lighting, wireless electrical energy transmission and antigravity.
WARNING:- Some of these experiments operate directly from 240VAC mains supply or far higher voltages at high currents are potentially lethal. Do not build unless you know exactly what you are doing. Do not touch any part of the equipment while it is plugged into a mains outlet. And remember that the methods described do not conform to any electrical safety standard and many of the experiments performed are downright dangerous.
Powerful magnets such as neodymium magnets or powerful magnetic fields generated by coils can be dangerous and not to be played with. Powerful magnets or magnetic fields can crush fingers. The power of magnetism can also cause chunks of metal to take flight and cause injury to body parts and or blindness.
Rotating machinery can pose a danger from rotating or reciprocating parts. Particularly when machine parts move toward each other, or one part moves past another, which can crush limbs.
Extremely intense sounds can burst ear drums or can be physically painful to human ears. High-intensity ultrasound waves are extremely dangerous to experiment with as they can heat human eyes or other tissue by absorbing ultrasound energy which becomes heat by vibration and corresponding energy loss.
Exposure to radio frequency energy or ionizing radiation that can be generated by coils can not only burn as they get hot but also cause radiation burns, damage to the skin or other biological tissue.
Direct skin contact with liquid nitrogen will cause severe frostbite (cryogenic or cold burns). This may happen almost instantly on contact, there is always a potential hazard when handling liquid nitrogen.
Be careful! Use good solid judgement in your work, and think ahead. I John Iwaszko do not endorse the experiments shown, and am merely passing on information, I have learnt through experiment. Safety is your responsibility!

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

[JOHNROMANIWASZKO]

@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

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

[JOHNROMANIWASZKO]

@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

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.

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

[AVAMagneticlev]

Very nice work.
