There is a magnetic force btw railway track and railwheel?
Answers
Answer:
No magnetic field, with the possible exception of an electromagnetic pulse from a nuclear blast, would disable a car.
Neither trains nor train tracks emit a significant magnetic field.
A magnetic field drops off extremely rapidly, based on the square of the distance from the source.
So, given the fact that a train does not emit a significant magnetic field and that a magnetic field drops off rapidly from its source, we can assume the magnetic forces from the train do not exert influence on their environment. Further, we know the car is designed to be impervious to any typically occurring magnetic fields. Therefore, we can safely conclude that this theory was cooked up by somebody with an ignorance of both magnetism and automobiles and should lend it no credence to it whatsoever.
Answer:
yes there is a magnetic force between railway track and rail wheel
