Do clocks tick at different rates in different magnetic fields .
Do magnetic fields affect the speed of light in the Pound-Rebka experiment?
- Thread starter cragar
- Start date
In summary, the conversation discusses the effects of different magnetic fields on clocks and light. The speaker mentions their watch stopping in a 1.5 T magnetic field and questions whether this relates to the Pound-Rebka experiment. They also ponder the possibility of measuring a gravitational shift in light traveling from a stronger to a weaker magnetic field due to the energy density of the magnetic field creating a gravitational field. The question of whether photons interact with magnetic fields is also brought up.

nice , If we try to relate this to the pound-rebka experiment , when they tried to measure the gravitational shift of light , If we wanted to expand this to light traveling from a stronger magnetic field to a weaker one , I don’t think we would measure a shift in the light because photons do not interact with magnetic fields at least i think , But would we measure a shift because the magnetic field has an energy density therefore it would have a gravitational field , so would we then measure a shift in the light .
FAQ: Do magnetic fields affect the speed of light in the Pound-Rebka experiment?
What is a magnetic field?
A magnetic field is a region in space where magnetic forces can be detected. It is created by moving electric charges, such as the movement of electrons in an atom or the flow of electricity through a wire.
How do magnetic fields affect clocks?
Magnetic fields can affect clocks by causing them to run slower or faster. This is because the magnetic field can interfere with the mechanism inside the clock that keeps time. In some cases, a strong magnetic field can even stop a clock from working altogether.
Can magnetic fields be used to power clocks?
Yes, magnetic fields can be used to power clocks. This is known as an electromagnetic clock and it works by using the magnetic force between two magnets to create movement in the clock's mechanism. However, most modern clocks use batteries or electricity as a power source.
How do scientists measure magnetic fields?
Scientists measure magnetic fields using a device called a magnetometer. This instrument can detect and measure the strength and direction of a magnetic field. Magnetometers are used in many fields of science, including geology, oceanography, and astronomy.
Can magnetic fields affect human health?
There is ongoing research on the potential effects of magnetic fields on human health. Some studies have suggested that exposure to strong magnetic fields may have negative health effects, but more research is needed to fully understand the impact. However, the magnetic fields produced by everyday objects, such as clocks and electronics, are not strong enough to cause harm.
