Title: Do magnetic fields effect the flow of time?
Post by: benm on 15/04/2019 14:25:52
David has a timely question:

Within the boundaries of a Magnetic Field (say if you were positioned on top of the magnetic north pole) would time increase or decrease or remain the same?

Can anybody help?

Well :)

What is the mass?

Gravity is more at the earths poles than it is at the equator due to the earths rotation ie centripetal force.

Time runs slower as gravity increases.

So one might think that time runs slower at the poles, because of the small increase in gravity, however the equator is moving with respect to the poles and cancels out any time difference. So clocks at the equator and poles at the same altitude run at the same rate. The earths magnetic field is too weak to affect the tick rate of atomic clocks. 


However a clock on a mountain top runs faster than one at the bottom of a mountain, people living at the top of tower block age faster https://www.dailymail.co.uk/sciencetech/article-1314656/Scientists-prove-time-really-does-pass-quicker-higher-altitude.html

Actually. rereading this question?
What is it it asks?

About Earths gravity at the magnetic north and south pole?
Or is it if a magnetic field can have gravity?

It seems like a unholy mixture here?

Or maybe

The title says "do magnetic fields effect the flow of time"

Magnetic fields can cause clocks to become inaccurate, I don't think there is any extant theory that indicates magnetism actually slows time. It is well known that gravity slows time as measured in atomic clocks, magnetism can also affect the frequency of atomic clocks. It is altered slightly by gravity, magnetic fields, electrical fields, force, motion, temperature and other phenomena. https://en.wikipedia.org/wiki/Atomic_clock

Although the magnetic fields that we can generate in the laboratory are inadequate to produce any measurable effect I believe the vastly greater fields produced by magna stars by the mass energy relationship do produce a considerable effect.
