Is it possible to use magnetism to propel cars, aircraft, and turbines that produce electricity?
I know satellites use magnetic fields of planets to aid in their trajectories and propulsion, but could this same theory be used for more common purposes such as aircraft and cars?
For instance, say if you had a positviely charged magnet, and your vehicle is negatively charged. Could you place the positive magnet in front of the vehicle and it follow the magnet i.e. holding a carrot in front of a donkey?
How about if you had a positively charge magnet and the vehicle is positively charged and you put the magnet behind the vehicle. Would the alike forces cause the car to keep moving?
Could these magnetic forces be used to spin turbines instead of the steam created by boiling water with dangerous nuclear fuel rods? I guess in order to power the magnets you’d have to use electricity which in turn would be counter productive, but is there another way
By no means am I a physics expert or pretend to be, but can some of you that are experts explain why this is or isn’t possible
Yea but is there away to harness or amplify the energy of the magnetic attraction to create propulsion is what I’m getting at?
I see what you mean. Somehow something would have to push the magnets to keep the car moving. Back to the drawing board…
Scratch the car idea. How about the turbine? Same principal applies?
Specifically, you need to study the difference between "force" and "work".
Already done
motors use fields to rotate
Trains use magnets to levitate (mono rails)
The other thing you need to understand to create energy
you need to supply fuel
You have nothing that produces ENERGY
You do not get ANYTHING for free
and in order to answer your questions you need a better understanding of physics
Theoretically, I would think it is possible. But, you need a strong magnet to achieve the propulsion.
To make the magnet stronger, what you need is to charge it, usually using electricity. This would probably have 2 issues with it:
1: How do you charge it… where do you get access to the required electricity, without cables.
2: You just wont get the required bang for your buck. It will cost more to magnetize than the cost of gas.
Like the idea, the problem is that you would need energy to move the magnet in the Carrot on the stick idea.
This energy would be as much or more than if you powered the car itself…… Same goes for the push idea.
Consider if you built a model….if you push a model car along a track or place a magnet on it and hold another magnet of opposite charge in your hand, although you would not be physically pushing the car the energy required to push the pushing magnet would be as much than if you where pushing the car itself, as that magnet has to push the car even though it may have an invisible conection to the car….if you see what I mean !
Either way, the amount of energy you use to continually reposition these magnets is always greater than the total energy output of this system, because your efficiency is always less than 100%.
