better yet have some non conductive mass in the center of a toroidal HV HF coil, and have the discharge pass out of a cathode on the top of the mass, ionizing the air molecules and making them positive, and have them move around the outside of the device and back towards the center below the device towards an anode. Not only does a similar effect occur, but the ions colide with neutral air molecules and produce a net upwards force on the device
Enter that thing in nasa's robot up a teather compertition.. although i guess you would need to suspend an extremely long coil with AC running through it ,
Better yet, why not create a spinning plasma inside a HV AC toroidal coil, creating the same effect.
If you had a high voltage/high frequency discharge moving from a cathode on the top/center of the ring magnet to an anode, bottom/center of the ring magnet, you that move the ring magnet upwards, as the discharge is indipendant to the device
what is happening is that the electricity goes through the coil creating an electromagnet. when the ac goes through it alernates the electromagnet creating a flux and creating a current in the ring. teh current is then opposed to the electromanet so it goes up. the dc had a short jump because there is no flux, but it goes from zero to whatever the current is and in that time the ring has a current and flys. When there is a cut in the ring the circut is not completed so its then a no go.
i suppose i said similar to what you said yourself. Although only a pure inductor has a 90 degree lag, as in an inductor with zero resistance or impedence. In practice thats not possible. Your right in that the ring will keep going up, as the ac current reverses, so does the induced current in the ring, so still opposes in the same direction
well its not exactly accurate although close. When dc is connected you have an initial changing magnetic field- as the dc current rapidly changes from zero to full current flow, this change in magnetic field induces current in the ring and it jumps. But the dc current reaches a peak and is then steady non changing current, therefor can no longer induce current in the ring. In the ac current, the magnetic field is constantly changing, therefor current constantly induced in the ring, so keeps goin
is the ac a stronger (voltage?) i dont know the right word, but is the ac delivering more of a current then the dc or are they =? because wouldn't it be logical if the current strength is = the ac is a stronger force?
No man, AC and CD have the same power, the only difference is AC power alternates backwards and forwards. The nasty bad guy in the video is electrocuting a poor flea under the ring, every time he shocks the flea, it kicks the ring. When he applies AC voltage, the flea kick's vigorously (60 times a second) thus making the ring go higher.
the ring responds to a CHANGING MAGNETIC FIELD by creating a current through it OPPOSING the change in the magnetic field and thus pushing itself upwards. current running through the coil creates a magnetic field primarily INSIDE the coil. an applied dc voltage will only have an INITIAL CHANGE in magnetic field and thus current will run through the ring until there is no change in magnetic field. AC will always change the magnetic field and so the ring continues to push itself upward
Where are your safety goggles? You get an F for doing this elaborate and potentially dangerous experiment without safety glasses. Fine example for the high schoolers out there.
nice

what voltage of AC and DC. The same? was the ring frozen whem you applied AC?

Quick question.. In this experiment would there be an equal and opposite force acting back on the apparatus when the powers turned on?
p3x797 2 years ago
for EVERY force, there is equal and opposite
