Mislim da je to neizvodljivo, jer koliko sam gledao National Geographic Megastructures, uvek su nekim ogromnim kranovima dizali predmete od 100 tona,recimo onim kranom Titan, nikako elektromagnetima. A da postoje toliko veliki elektromagneti koji bi to mogli, mislim da postoje u CERN-u. Ali su oni ogromni i sami teski nekoliko desetina tona,

Ne mogu da verujem da na ES-u niko ne moze decku
da izracuna struju koja je potrebna da se odredjena
masa podigne elektromagnetom na visinu h, ako je G 9.81.

Ajmo ljudi pa da se predje na razmatranje budzeta.

Java Beograd:
Može, relativno je lako izvodljivo, pod uslovom da imaš dovoljno jako napajanje. Čak, za ovako velike struje, isplati se energiju izvora trošiti na hlađenje superprovodnika do kojih će se sastojati elektromagnet, umesto da se strujom pogoni elektromagnet od bakarnih provodnika.
Cena ne bi trebalo da pređe 40-50 miliona dolara. Jedini problem je naći dovoljno jaku dizalicu koja je u stanju da podigne elektromagnet, koji treba da podigne predmet težak 100 tona. Po mojoj proceni elektromagnet bi trebalo da je težak oko 100 tona, takođe,

Okmijun: ne bre, ne dizem ga tako sto je el.magnet GORE
VEC je el. magnet u betonu, na zemlji, a predmet od 100ak T, lezi na njemu, ukljucimo ON/ OFF, i voila!
odlete nas teg od 100t u vazduh! to me zanima....
a kolko je to sve opasno za prisusvo ljudi?

Shadowed:Nigde ne kaze da je predmet od gvozdja kao ni da ne sadrzi (elektro)magnet u sebi.

DA LI JE MOGUCE POSLATI NEKI PREDMET od 100t na VISINU OD 100m DANASNJOM LJUDSKOM TEHNIKOM?

.sasa.:


Mozda nekom velikom raketom?

Okmijun: ne citas temu ili mislis da si duhovit?

Nabukodonosor:
Pitaj Waltera i Jesse-a, upravo su pravili neki slican magnet.

Okmijun:
teoretski, bilo kako?

Okmijun: Nisam bre nikad ni menjao sta ocu.....

@Okmijun
Dakle, moguce li je izvesti GIGANTSKI ELEKTROMAGNET koji bi predmet od 100-200t drzao na visini od 100-200m ili makar 60-70?

pa tako nesto mi i treba, nek kosta kolko kosta, al da radi.

@Okmijun
A jel postojio bilo koji nacin da nesto levitira od bilo cega u vaduhu na 100m visine i 100t tesko?
SF?

etjen:
mislim da je mnogo izvodljivije angažovati Koperfilda da hiptnotiše sve prisutne kako to što si zamislio radi

Sceka:






I tako dalje, mrzi me vise. Ne znam ni sto sam ovo postavio, umorih se.

Electromagnetic suspension
Main article: Electromagnetic suspension
In current electromagnetic suspension (EMS) systems, the train levitates above a steel rail while electromagnets, attached to the train, are oriented toward the rail from below. The system is typically arranged on a series of C-shaped arms, with the upper portion of the arm attached to the vehicle, and the lower inside edge containing the magnets. The rail is situated between the upper and lower edges.
Magnetic attraction varies inversely with the cube of distance, so minor changes in distance between the magnets and the rail produce greatly varying forces. These changes in force are dynamically unstable – if there is a slight divergence from the optimum position, the tendency will be to exacerbate this, and complex systems of feedback control are required to maintain a train at a constant distance from the track, (approximately 15 millimeters (0.59 in)).[25][26]
The major advantage to suspended maglev systems is that they work at all speeds, unlike electrodynamic systems which only work at a minimum speed of about 30 km/h (19 mph). This eliminates the need for a separate low-speed suspension system, and can simplify the track layout as a result. On the downside, the dynamic instability of the system demands high tolerances of the track, which can offset, or eliminate this advantage. Laithwaite, highly skeptical of the concept, was concerned that in order to make a track with the required tolerances, the gap between the magnets and rail would have to be increased to the point where the magnets would be unreasonably large.[24] In practice, this problem was addressed through increased performance of the feedback systems, which allow the system to run with close tolerances.
[edit]Electrodynamic suspension
Main article: electrodynamic suspension


JR-Maglev EDS suspension is due to the magnetic fields induced either side of the vehicle by the passage of the vehicle's superconducting magnets.


EDS Maglev propulsion via propulsion coils
In electrodynamic suspension (EDS), both the guideway and the train exert a magnetic field, and the train is levitated by the repulsive and attractive force between these magnetic fields.[27] In some configurations, the train can be levitated only by repulsive force. In the early stages of JR-Maglev development in Miyazaki test track, a repulsive system was used, instead[28]. This fact sometimes causes conception that the EDS system is a repulsive one, but that is not true. The magnetic field in the train is produced by either superconducting magnets (as in JR–Maglev) or by an array of permanent magnets (as in Inductrack). The repulsive and attractive force in the track is created by an induced magnetic field in wires or other conducting strips in the track. A major advantage of the EDS maglev systems is that they are naturally stable – minor narrowing in distance between the track and the magnets creates strong forces to repel the magnets back to their original position, while a slight increase in distance greatly reduces the repulsive force and again returns the vehicle to the right separation.[24] In addition, the attractive force varies in the opposite manner, providing the same adjustment effects. No feedback control is needed.
EDS systems have a major downside as well. At slow speeds, the current induced in these coils and the resultant magnetic flux is not large enough to support the weight of the train. For this reason, the train must have wheels or some other form of landing gear to support the train until it reaches a speed that can sustain levitation. Since a train may stop at any location, due to equipment problems for instance, the entire track must be able to support both low-speed and high-speed operation. Another downside is that the EDS system naturally creates a field in the track in front and to the rear of the lift magnets, which acts against the magnets and creates a form of drag. This is generally only a concern at low speeds (This is one of the reasons why JR abandoned repulsive system and adopted sidewall levitation system.[28]); at higher speeds the effect does not have time to build to its full potential and other forms of drag dominate.[24]
The drag force can be used to the electrodynamic system's advantage, however, as it creates a varying force in the rails that can be used as a reactionary system to drive the train, without the need for a separate reaction plate, as in most linear motor systems. Laithwaite led development of such "traverse-flux" systems at his Imperial College laboratory.[24] Alternatively, propulsion coils on the guideway are used to exert a force on the magnets in the train and make the train move forward. The propulsion coils that exert a force on the train are effectively a linear motor: an alternating current through the coils generates a continuously varying magnetic field that moves forward along the track. The frequency of the alternating current is synchronized to match the speed of the train. The offset between the field exerted by magnets on the train and the applied field creates a force moving the train forward
