If you put a magnet inside a coil and spin the surface they both are over, will this generat...
A changing magnetic field induces an electric current in a coil. If you cross a magnet through the coil it will induce a current, but if the magnet is at rest relative to the coil there will be no cur …

Could gravity around rotating bodies make them pull apart rather than attract? Due to the gr...
This new gravitational field is necessary because of relativity and how electromagnetism works, it is the explanation of how two observers agree on the result of some experiments involving gravity and … electromagnetism. …

Same Mass But Less Gravitational Effect Due To Electric Charge?
The Schwarzschild metric describes a spherical, eternal, static black hole with no rotation and no electrical charge, so it can be used to understand gravity around objects with negligible rotations ( …

Do Electrically Neutral Black Holes Interact With a Charge's Electromagnetic Field?
I've been wondering if it's possible for a black hole to interfere with the electromagnetic field of an electric charge, without the black hole itself having an electric charge.
Imagine that there is …

The Relation Between Maxwell's Equations and the Equations of Gravitoelectromagnetism
Under certain conditions, it is possible to approximate the effects of the theory of relativity through equations very similar to those of Maxwell, but for gravity. In these equations, our "standard" …
