Gravity Machine

You'd become Copperman. Like Ironman, you'd have no natural superpowers, but using your money you created something that will make you special.

oh... hey

Die, as all the magnets snap together haphazardly, destroying your limbs and body in the process.

woah, i would never do that.

Shit man, you know I didn't mean it that way. Cats meow, dogs bark, neodymium magnets pinch everything you love. It's just nature's way

but i love you

I love you too, but this relationship was toxic to begin with...
Magnets... I just don't know how you fucking work

why won't you love me

I once blew up a balloon, and put two magnets on either side of it. The balloon blew up with such force that one magnet flew out the window, never to be seen again, and the other lodged itself into a wall.

Did you leave it there as a warning that you are a magnet-balloon shuriken master?

If by leave it there you mean physically unable to remove it, then yes.

I'm on it!

there is still gravity the guy was joking when he said anti gravity machine

I'd like to point out that there are very many antigravity machines out there. Probably the most common one has existed for much longer than humans. This incredible invention is most often referred to as "the knee". Other common ones are known as "planes", "elevators", and "helicopters".

In all seriousness though, an antigravity machine would be any machine that works against gravity. Which is what's happening in all the examples I've provided. And it works here too. The induced current (and connected magnetic field) work to oppose the magnet's motion which in this case is caused by gravity. Hence: Anti-gravity.

technically you are correct but that type of anti-gravity is the literal meaning (against gravity) however most of the time anti gravity means no gravity in which there nothing pulling down on the object or seemingly no gravity ie: free-fall, in the case of your description of anti gravity there is still a downward pull it just isn't pulling the entire thing down because frankly gravity isn't that simple other wise mountains and oceans and valleys wouldn't exist the entire planet would be covered with shallow water and even then the world would have to be a perfect sphere unlike how it is now as it is flat at the poles and bulging in the centre. you would the have to consider the entire earth anti gravity which of course is impossible since it's the source of it's own gravity. take away the sun and give the earth a few billion years and that would happen except with ice instead of water. that is why you are also wrong because that description is not the scientific description, you mention how the magnetic field works against gravity but that is not completely defying gravity, that is obviously why it still falls. Im a physics teacher btw (not to sound like those 12 year olds who pretend to be navy seals) also sorry if this makes little sence im terrible at describing things on the computer

check your grammer

ascend down?

I think ascend means a type of transport when I'm tired

Didn't Tesla do something like that?

yes, it works, but the magnets will wear out so fast that it has no practical use.

If you're talking about applying this to a car, then no.

If you're talking about applying it to a generator to create (essentially) free power, then maybe.

nothing, because gravity goes down

ahhh, i assumed the magnet would stay in place floating in the middle.
Thanks for clearing that up.

It's an interesting phenomenon. If you don't mind I'll explain it briefly:
-The moving magnet induces a current in the copper pipe. A changing magnetic field will induce a current in any conductor, but it's really only in a pipe that you'll see this "antigravity".
-A current in any conductor creates a magnetic field.
-In the case of a changing magnetic field, the induced magnetic field will oppose the initial change in magnetic field which creates it.
-Since the initial magnetic field is moving downwards, the induced magnetic field will attempt to halt its motion by forcing it upwards.
-Due to some complicated physics stuff, the induced magnetic field cannot halt the motion of the falling magnet. But it can slow it down.
While Mr. Fiction was correct, he didn't really explain why this wouldn't happen. On second thought, I haven't either. The reason it wouldn't is because the magnet wouldn't be moving, and without a changing magnetic field there would be no induced current, and therefore no induced magnetic field.

whoa, science is awesome.
