Talking about charges. If someone claims that in his work time reversal symmetry is conserved, does that equal to say he/she is not imposing a magnetic field?
JHamm said:Time reversal symmetry means that if you had recorded the situation and played the tape backwards things would "make sense" in that you could believe that was what really happened (watching some Brownian motion in reverse would make sense, watching a bowling ball slide back up the lane and then launch itself into your hand doesn't). So how do you think this applies to magnetic fields?
Time reversal symmetry is a fundamental physical principle that states that the laws of physics remain unchanged when the direction of time is reversed. This means that physical processes should behave the same way if time is moving forward or backward.
Magnetic fields can break the time reversal symmetry. This is because they are created by moving electric charges, and the direction of the magnetic field is dependent on the direction of the current flow. Reversing the direction of time would also reverse the direction of the current and thus the direction of the magnetic field.
Charges play a crucial role in time reversal symmetry. In order for a physical process to be time reversal symmetric, the charges involved must also be symmetric. This means that the charges must behave the same way if time is moving forward or backward.
Yes, there are certain physical processes that violate time reversal symmetry. One example is the decay of subatomic particles, which tends to happen more frequently in one direction of time than the other. This violation of time reversal symmetry is known as CP violation.
Time reversal symmetry is an important concept in many areas of physics, including particle physics, quantum mechanics, and cosmology. Scientists use this principle to study the behavior of particles and systems in different time frames, which can provide valuable insights into the fundamental laws of nature.
