So I kinda have an idea for a magnetic car;

Say you have a car out of metal or whatever that's magnetic, and you put a one of those huge U-shaped magnets like a few inches from the front of the hood with a bar or something. Wouldn't the magnet attract the car and drag it forward? I know it would have to be one hell of a magnet to do that, but is the idea correct? Oh and also they'd have to find a way to have you adjust the magnetic force or whatever so you can brake.

well yes it would work if the magnet was strong enough but the magnets got to be moving in teh first place, so its flawed in that concept


Yeah that's what I couldn't get my head around too but I mean the magnet is attached to the car so if the magnet pulls the car forward then the magnet goes forward too so **** this is confusing.
#5
If the magnet was on something that moved, it could possibly work.. but It seems like it'd cost too much money...

I think we should get land speeders like in Star Wars..

It would, but then it would attach and then stop.

Now if they attached a moving magnet to the road, then you would go places.


lol @ the ambiguity in your speech.

I the magnet is attached to the car, it would pull on the car, but it would not go anywhere. The mount to hold the magnet in place would not move. The magnet would need to move forward along the road.

the force would cancel out because the one in front would try to move back while the one in back would try to move forward.

they have them magnetic trains in japan, that reduce friction to save energy. Now suppose you placed magnets in the roads, and had a tiny jet engine in the car and you could have land speeders....

Study up on Newton's laws of motion. The car would be pulling the magnet as well.

If you mounted a magnet on the axle, connected to the wheels, with the ability to rotate you could in theory make the car move by exploiting the repelling force another magnet could exert on that magnet

its not that it wouldn't work, its just that it would be very impractical.

I've had similar idea's but a magnet of the scale that is needed would affect electro-magnetic equipment, people who had braces maybe (whether in their teeth or to set broken bones) and we'd have to start making everything out of plastic.

cars are magnetic my L plates have magnetic things that allow me to stick them to my car without getting glue on the paintwork

nice idea kinda like holding a carrot in front of a donkey so it goes for the carrot. but magnets are different things. first you'd need an incredibly powered magnet but maybe for the future you never know . try some small scale tests with say a tiny magnetic car with the same idea. It might work i dunno much about physics and things like that but give it a try never know

Youd have to have the second magnet attacked to the front of the car but a few metres ahead. Even then im not sure how it would work. Interesting idea though.

Here's an example of how it wouldn't work: you can pick up your own weight right? Or at least move it? Now get in a plastic bag and try and pick yourself up.

Actually the point is that it's not the magnet that pulls the car, it's the car that attracts the magnet.

Take a really strong magnet, and take a fridge. Throw the magnet in the air near the fridge.
Result: Magnet attaches to fridge.

If you put a magnet on a stick and the stick in front of a car, then the magnet would try to get on the car, not the car trying to get on the magnet. Unless that magnet is like heavier than the car itself. But that's just ridiculous, man!

thats the short answer.... the long answer requires some physics and the definition of an engineering system

now mag lev technology for cars, thats a good idea. it would just require the overhaul of everything you think a road is

No, they both attract each other but the smaller magnet requires less force to move, if you had a magnet that meant a strong enough force and cemented it into a wall and put a car in front of it (and it would have to be a very strong magnet) then the car doesn't stay still while the magnet rips out of the wall, the car comes to the magnet as it requires less force to move.

God some people on UG really have no idea of basic physics or logic. (not just to you I have quoted)

Dear Idiots.

The magnetic car idea works like a dream. All you have to have is two magnets repelling eachother. The repulsion pushes the car forwards.

Just have a look here

and you'll see a magnetic car working perfectly.
