If you have a cold enough superconductor with a powerful enough charging going through it could it be possible to create an electromagnetic force that will repeal Earth’s electromagnetic field countering the force of gravity?

>>10887172
yes, you can hover things a little off the ground. you’re for sure not going to blast off into space though, realistically, that’s why rockets exist

>> No.10887250

>>10887172
thats not anti-gravity tho

>> No.10887255

>>10887172
no, because the earth's magnetic field is only oriented in one particular direction

>> No.10887530

>>10887255
So what if the superconductor had the opposite orientation?

>> No.10887549

>>10887172
Absolutely but the energy requirement makes this non feasible.

>> No.10887551

>>10887530
then that has nothing to do with antigravity. what you are describing is the same mechanism that makes compasses work, btw, which have existed for more than a thousand years.

>> No.10887595

>>10887551
Not really compasses work because they are attracted to the magnetic field of the earth. I’m curious about something that repels it

you are talking about magnetism but you call this "antigravity"....are you really this novice to this subjects?

btw I think magnetic levitation would work best at the earth poles.

>> No.10887800

>>10887172
Quite possibly, if you twist the fields enough. Look into gravitomagnetic London moment

>force of gravity
It's an acceleration.

It's mutually impelled by the earth to align with it. It's not "attracted" at at. It came from the earth to begin with.

>I’m curious about something that repels it.
Like polarities "repel", but only if they're forced to attract the wrong way. What I mean by that is that without humans or anything but the environment to force those polarities the wrong way, it will never happen. Each magnet would just rebound and impel each other into 1 magnet that works as one magnet. They would just keep accelerating into each other.

Explain the difference

>>10887250
"anti-gravity" is basically "no acceleration". Inertia.

I saw a japan antigravity howerboard on youtube which was working with cold superconductor.
