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 ...

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 ...

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&...

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 ...

Where is magnetic field for gravity? [duplicate]
Reading the book called "The great design particles fields and creation" one finds the following paragraph
In a universe like ours, constructed of electrically charged elements, magnetism ...

Why don't ferrous metals fall to earth faster than other objects?
Given that gravity is a weak force compared with magnetism and given the fact that the earth is a magnet, why don't ferrous metals fall to earth faster than other objects? Seems like they should!

Can my theory work for letting the swinging work?
This is my theory, will it stop after few hours? why would it stop? i have on top S to S to repel then i have N S to attract, to produce random force for the swing. Then i have large N N repel to push ...

Are static magnetic and electric fields distorted by gravity? How?
Suppose we have a pointed electric charge or a bipolar magnet. If we put a massive gravity source nearby, will the magnetic and electric fields be distorted? In what way?

Does energy of photon change due to some external magnetic field?
I came to know about the energy of photon changes (decreases) while going away from the emitter (even from earth) due to gravitational field effects.
Is there any change in energy/wavelength of a ...

Electron traveling through gravitational and magnetic field
When an electron travels through a magnetic field it experiences the Lorentz force. The force acting on the electron causes an acceleration and therefore Cyclotron radiation is emitted. After reading ...

If light is affected by gravity, does that mean gravity affects electrical&magnetic fields too?
Since we observed that masses indeed bend the light, and since we consider light to be composed of electrical and magnetic fields, does that mean a single point charge will result with bent electrical ...

Why can a magnet setup not fly?
I know that the following setup won't work to lift it up forever:
But I'm struggling to convince myself why. If the top magnet is strong enough to lift the weight, why is the bottom magnet not ...

Why is there no gravitational magnetic field? (Or, is there?)
We can think that the electric field and the gravitational field operate similarly in the sense that the forms of their governing laws (namely, Coulomb's law and Newton's law respectively) are ...
