could magnetism ever be used to power automobiles?

Question

to a point where that was the only thing to make them run

Answer 1

Not unless someone figures out how to build a perpetual motion machine. At this point in time it seems impossible, but you never know I guess. Magnets are only useful for generating energy in the dynamic case (i.e., when they're moving). That's how power generators work, they convert one type of energy (whether its heat from burning fossil fuels, moving water ect.) into electricity by moving a coil of wire in a magnetic field. So in other words, you can't create energy from nothing. Magnets only have energy when they're moving, and they're only moving when acted upon by another force which is cause by another type of energy.

Answer 2

If you mean the pull of permanent magnets, no. Such magnetism is a force, not a source of energy. But if you mean electromagnetism, yes, that might be possible, but you would still have to supply the energy from somewhere.

Answer 3

Permanent magnetism is a force, not a source of energy, hence it could not be done from that. It is possible from electromagnetism, but in that case also electrical energy is the prime source not the magnetic one.

Answer 4

yes......in fact its japan i think that has a train that runs on magnetic propultion....so yes i think its posible for cars, since they are coming out with cars that run on a beam radar, and the car runs itself down the interstate...its in the makking, but in thenear future

Answer 5

The word fission skill to chop up aside. interior the reactor of an atomic skill plant, uranium atoms are chop up aside in a controlled chain reaction. In a chain reaction, debris released by skill of the splitting of the atom bypass off and strike different uranium atoms splitting those. those debris given off chop up nevertheless different atoms in a chain reaction. In nuclear skill plant life, administration rods are used to maintain the splitting regulated so it does not bypass too quickly. If the reaction isn't controlled, you may desire to have an atomic bomb. yet in atomic bombs, exceedingly much organic products of the element Uranium-235 or Plutonium, of an actual mass and shape, could desire to be extra mutually and held mutually, with great stress. those situations are no longer present day in a nuclear reactor. The reaction additionally creates radioactive cloth. This cloth could desire to wreck people if released, so it rather is saved in a sturdy sort. The very sturdy concrete dome interior the photograph is designed to maintain this cloth interior if an twist of destiny occurs. yet another variety of nuclear potential is termed fusion. Fusion skill turning out to be a member of smaller nuclei (the plural of nucleus) to make a greater nucleus. The sunlight makes use of nuclear fusion of hydrogen atoms into helium atoms. this provides off warmth and gentle-weight and different radiation. interior the photograph to the the appropriate option, 2 styles of hydrogen atoms, deuterium and tritium, integrate to make a helium atom and one greater particle called a neutron. additionally given off in this fusion reaction is potential! thank you to the college of California, Berkeley for the photograph. Scientists have been engaged on controlling nuclear fusion for an prolonged time, attempting to make a fusion reactor to offer electrical energy. yet they have been having worry discovering the thank you to regulate the reaction in a contained area. what's greater advantageous approximately nuclear fusion is that it creates much less radioactive cloth than fission, and its furnish of gasoline can final longer than the sunlight. to you question WHY? Use the stress!
