Dual of Newtonian gravitational field
In the static state, the laws of Newtonian gravity and Coulomb force have exactly same formulas,
$$F = K \frac{A_1A_2}{r^2}.$$
In the electrical case, moving materials produce a field, say a dual ...

Is there an upper boundary to magnetism?
This is gonna take some explaining, and full disclosure: I'm still undergrad, so please, forgive my ignorance here. Though please also hear me out: magnetism, like gravity, falls off with distance, ...

New "gravity force" analogous to magnetic force?
I was watching Eugene Khutoryansky's physics video about Einstein's Gravito-Electromagnetism, Gravity of moving mass in General Relativity
. In that, he discussed why maxwell's electromagnetism laws ...

Is gravity the result of protons and electrons? [closed]
I understand that gravity is the result of a curved space/time caused by mass. But is it possible that gravity is the result of protons and electrons magneticly interacting on a massive scale? Large ...

Is it possible to make a magnetic box that will compensate Earth gravity allowing magnetic objects inside to fly on orbits like in space? [closed]
Is it possible to simulate solar system using magnetic spheres and some kind of box that will compensate the Earth gravity by magnetic force?

Does electric field really exist or it is just an interpretation? [duplicate]
Did physicist create the concept of electric field to describe the interaction of charge particles at a distance? If they are real, do we have experimental evidence? Please describe some of them. And ...

Gravito-magnetism and gravitational waves outside of General Relativity
An important implication of (linearised) Einstein equations is that you can write a gravito-magnetic field in addition to the gravito-electric field (the classic gravitational field). And from there ...

Does a Magnetar have a magnetic event horizon different than it's schwarzchild radius?
Being the strongest magnets in the universe I think there would be a point of know return different for a neodymium magnets then that of similar non magnetic mass.

Why do the sensitivities of magnetometers and gravimiters have such strange units?
It looks like the sensitivities of magnetometers and gravimeters are usually reported with the units of $\text{Tesla}/\sqrt{\text{Hz}}$ and $\text{Gal}/\sqrt{\text{Hz}}$, respectively (where "Gal&...

Do magnetic things fall faster?
Assuming correct orientation, do magnetic things fall faster than non-magnetic ones because of the magnetic field of the Earth? Of course it is clear that if any, the effect is very very small, but ...

Can a gravitational field be focused like a magnetic field?
A pyramidal magnet will focus a greater magnetic field at the top of the pyramid than at the bottom. See video here Is there any evidence that the same holds for a gravitational field? Perhaps the ...

Does gravity induce charges to form magnetic fields?
We all know that moving electric charges produce magnetic fields. Gravity is said to be equivalent to acceleration which implies movement. Does this mean that an outside observer will see an ...
