# What is the time dilation less a magnetic field?

Does time dilation drop off like a gravity or does resemble a magnetic field model?

Could a smaller body with a magnetic field have more time dilation then a larger body without and to what degree?

• To talk meaningfully about time dilation you need to define both the observer and the observed. Also I think you mean "correlation" not "coalition" – Steve Linton Jun 28 '19 at 20:09
• Relative to a clock on the ground, General Relativity says that a clock in orbit runs faster due to gravitational time dilation slowing down the ground level clock. But you also need to take into account the symmetrical time dilation due to relative speed, as predicted by Special Relativity. I'd rather not talk about magnetic fields in case I add to your confusion. ;) But basically, magnetic fields don't change the time dilation. – PM 2Ring Jun 28 '19 at 20:48
• Most large bodies have no magnetic field to speak of, yet the time dilation due to their gravity is quite measurable. So, no, you don't need to involve magnetic fields to get time dilation. – Florin Andrei Jun 29 '19 at 0:15
• What do you mean when you say "The range of the time dilation doesn't taper of like gravity but it does resemble the taper off of a magnetic field"? – HDE 226868 Jun 29 '19 at 17:12
• In the weak field limit gravitational time dilation depends on differences in the gravitational potential, so for point masses it scales by $1/r$. – dmckee --- ex-moderator kitten Jun 30 '19 at 4:50
