Question

Has there ever been a design that only used magnets as a power source to power a car?
I developed this design(only on paper so far) to power a car using nothing but magnets as a power source. Has this been done yet? If so was it successful, if not, why? The only major problem I can think of so far with this design is metal objects flying across the road being attracted to the car.

Answer 1

No of course not. If the magnets are on the car where would the location for their magnetic force be to get the car moving? Obviously not on the highway because that is not made of steel nor is it made of a series of opposing magnets.

If you think that the magnets can push the car just by their having a certain strength you are talking perpetual motion machine and no one who understands engineering will want to listen to that talk.

Answer 2

There are 2 distinctive methods of producing pass from magnets that I even have seen utilized in transportation. One is an basic generator that makes electrical energy to capability an electric powered motor vehicle. the midsection of a generator is a magnet. the subsequent up is used on some trains. It relys on a magnetic track and a custom resting on magnets with the similiar poles dealing with one yet another. The practice track magnets could properly be reversed. by employing reversing the magnets interior the track the practice could properly be attracted to those magnets. because of the fact the practice skipped over those magnets they're reversed back to being the comparable poles because of the fact the magnets below the practice. This keeps the practice floating interior the magnetic container. I observed something approximately this on "modern Marvels" on the historic previous Channel one evening.

Answer 3

Numerous designs have been tried to produce constant motion using only permanent magnets. So far, none has been successful. Electro-magnets can be controlled to produce motion - rotary or linear - but they, obviously, need an external power supply (electric current) which can be turned on and off or reversed in order to maintain the motion.

Permanent magnetic motion is an intriguing idea - and, contrary to what you may be told, it would not violate any physical laws - it would only convert the magnetic force to mechanical motion.

Answer 4

No. Power requires energy, such as the chemical energy stored in gasoline. Magnets have no energy store.
