If you ever talk to someone confused by this, maybe ask them to lightly push the front magnet in the direction it’s trying to go.
Young lady, in this house, we obey the laws of thermodynamics!
Did you try flipping the magnet over? If you put the two north ends together they’ll repel instead of attract.
The beauty is that you can make the mental gymnastics to make it work both ways.
If they are opposite, the magnet attracts the car which moves the magnet away creating infinite motion
If they are the same, the magnet is repelled by the car, moving it away, moving the car forward creating infinite motion
You can even do mental tricks to make the contraption go backwards: Opposites: car attacks magnet which moves the car backwards Same: magnet reppels the car which moves the contraption backwards
By your though process shouldn’t the car be going backwards?
So mount it on the back and make yourself an old-fashioned rear engine car.
Except it won’t be moving without outside force? The magnets are not getting closer from the wheels spinning
I am aware of that, I was going along with the joke.
I tried something like that when I was about ten.
I still hold feelings against the force range being so short. Too close and the wire bends. Too far and there is barely any attraction…
Ugh, I just want to break physics, let me be.
The wire/metal holding it needs to be springy and bobbing back and forth to generate the momentum, duh… Half-assed implementation I say.
Excellent! It is always nice to see people asking questions - the journey towards the answer should prove most enlightening! :-D
The magnet isn’t strong enough.
“No srsly y isnt it?”
Why would it? Think about it, would the two magnet gets closer if the wheels started rolling?
Not with that attitude they won’t.
Need a bigger magnet.
Also, how do they work?
Real, totally heavily simplified answer. All atoms could be magnets, but most don’t have a force because the electron orbitals aren’t out enough. In fact just about everything can be explained by what the electron orbitals are doing. Even why the chair you’re sitting in feels solid. It’s the orbitals. See
and the deeper lesson on knowing the right questions to ask.
I love listening to Richard Feynman talk in those interviews
No, atoms with a symmetrical subatomic structure could never be magnets! And what would be the point of somehow enlarging the electrons orbit? You surely know a magnet needs a positive pole!
You are also definitely wrong about your third statement!You could never explain anything based on just the electron cloud, much less physics; a whole scientific field that generally works with the atomic core
Missed the first sentence I guess. It’s why I included the video for a much better, although also simplified and incomplete answer, and he says why.
What did you oversimplify to get there? And so you understand thats nonsense but have had commented it regardless? Hope everyone is at an situation where they can watch that vid of urs, everyone else because I am not
Miracles
I am pretty sure the other guy is talking nonsense and he kinda didn’t explain anything, its basically an atom with such a subatomic structure where there are more electrons on one side than the other, making that side more negative! The whole deposit is made up of atoms facing the same way!
Oh boy, this is very incorrect, because it sounds like you are attempting to explain magnetism with electrostatic forces. Here is a basic model which separates the difference between the two:
-
Electrostatic forces are caused by the electric field. Something produces an electric field simply by having an unbalanced charge. Positive attracts negative, negative repels negative, positive repels positive.
-
Magnetic forces are caused by the magnetic field. Something produces a magnetic field by having an unbalanced charge AND is moving.
This is why when trying to explain how solid magnets work, we focus on the electrons because electrons are charged particles that are always moving. So they produce both an electric field (being charged) and a magnetic field (being a moving charged system).
Rhaedas is sorta correct. Any solid system has the capability of being a magnet, but this takes an incredible amount of physics work where iron is special. Iron’s electrons are able to easily maintain a synchronous orbit with each other which results in magnetic forces being observable at a macroscopic scale (seeing iron magnets pull on each other). In most other materials, the electrons orbits are chaotic, so even though magnetic fields are still being produced by their electrons, the lack of order results in no magnetic force being observable on the macroscopic scale; but if you place this non-iron material within a very strong magnetic field, you may be able to align their electrons orbits so that it becomes magnetic on the macroscopic scale (like iron).
Did you use ai to form that? No human has ever, ever written that magnetic force causes magnetic field; nor electrostatics force causes an electric field…
No, electrostatic fields is caused by stationary charges
I don’t dare imagine what you think an unbalanced charge is, but a moving electric charge is enough to cause a magnetic field.
‘It takes incredible amounts of physics work to get something’… You know, ai used to worry me quite a bit but comments like yours calm my soul! We are thankfully not there yet where it’s actually would be capable of replacing hack squat!
Not AI. I’m in academia, so I write academically.
I specify “physics work” to mean physic’s definition of work (dot product between Force and Displacement).
And to not connect the importance between the electric and magnetic field as it pertains to the the electrostatic force and magnetic force reveals your basic under of the physics. Hence, why your prior comment was so problematic…

Maybe it needs gas?
need two separate vehicles and two magnets, one weaker then the other
so the weaker one will repell the other and it will kick forward moving the other forward and rinse and repeat at a sonic speed
thats gotta generate some kinda motion
This is basically how a
rail cannoncoil gun works, just with electromagnets that can reverse their polarity.It’s a powerful way to accelerate anything — I think it’s most famously used in those types of metal roller coasters that start you at a flat-with-the-ground angle, and then just fuckin launch you up a ramp to 45° with electromagnets. The issue is that you need a fuckton of energy to do that.
What we need for true perpetual energy is to just capture that guy Blanka from Street Fighter.
You could get something like this to generate thrust in theory, just not enough to move an object with this much mass and air resistance. Also all of the work is being done on the rod suspending the magnet. It’s kind of similar to ionic propulsion.
