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 ...

How does this magnetic toy work?
A nephew of mine has this toy called "Gravitrax". It is basically a track building kit - you can build various tracks for iron balls which go through the track thanks to gravity.
However, there is ...

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?

If the Moon had gravity as strong as the Earth's, and a magnetic field, could it have supported life?
If the Moon had gravity as strong as Earth's, and a magnetic field, could it have supported life? Because if the Moon had as much gravity as Earth, it could have retained more water than is present ...

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 ...

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 ...

What is the physics of tilt compensation of an electronic compass
This question concerns the physics behind the implementation of electronic compasses to find the orientation of a device.
In the robotics community, 3-axis magnetometers are often used for this ...

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&...

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!

Could you use earth's magnetic field to build a hover skateboard? [closed]
In "Back to the Future" they use levitating anti-gravo skateboards without wheels which will be difficult to build, because there is no theory on how anti-gravity could be created.
A possible ...
