what is the result of change in gravitational flux?
As a change in magnetic flux results in induced EMF (electromotive force) likewise what is the result of a change in gravitational flux?
UPDATE: Gravitational flux according to me has only ...

Why doesn't a magnet on a refrigerator slide down?
Obviously gravity pulls objects towards the earth's surface. Now suppose I have a refrigerator and a magnet. The magnetic force is perpendicular to the gravitational force. So it is not counteracting ...

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 ...

What happens to atoms in extremely strong electromagnetic fields?
I know that strong gravitational fields on the order of neutron stars (at the crust) atoms get compressed so tightly, the empty space between them is significantly reduced and it becomes denser. (http:...

Faradays law for a falling magnet
If experimentally it can be proven that the velocity of a falling magnet through a coil is proportional to the emf induced, has it also been proven that dB/dt is proportional to the emf induced and ...

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 ...

Is there a relation between the magnetic field force of the earth and the gravitational force between the earth and other bodies? [closed]
According to Newton's Universal Law of gravitation, we can say that a huge body of mass will attract another body of mass within a short range, however, if both bodies are for instance magnetic, ...

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 ...
