spacetime curvatures......magnetic field,gravtitaional field,electric field are they sort of same?????........

Question

I mean whenever a mass is placed in spacetime it bends it causing gravitation anf time dialation around it right???

even magnetic field and electric field represent curved spacetime but why is it that magnetic fiel of a magnet attarcts or responds only to MAGNETIC substaneces? if its merely a curvature of spacetime all the "masses" should follow it and on nearing it should strike onto it..but its not quite so...
2)AND magnet repels like poles how is that..when its just a curve of space??? does space decide what type of matter sould follow it and in what directio0mn and manner?????


plz give full explanation..

fast!!

ok...if the Magnetic and Electric fields are not associated with space-time curves..then ->
We all know that if you place a magnet at some distance from another magnet in VACUUM then there'll be magnetic interaction between the two(attract or repel) then if u say spacetime if not affected by the "magnetism" of the magnet then how did the other magnet sense the information of presence of other one?????

Secondly we all know elctromagnetic waves can travel in vacuum ,but then its varying elec. and magnetic fields(perp. to each other n direct of prop.) so doesn't it suggest that spacetime bending might be involved in the transmission otherwise how could it TRAVEL??????????

cmmon somebody..reply to the details i've added recenlty..!!!!!!!!!!!!!

Answer 1

The curvature of space time is only associated with gravity. If you want some excellent material on this check out my bro Michio Kaku, easily one of the brightest and user friendly physicists out there at:

Magnetism is completely separate from gravity, and it's cause is not associated with space time. Magnetism is attributed to electrons which are normally positioned randomly in a substance. In a magnetic substance the electrons are more aligned than not creating a pull or repel from its poles. In the case of an electromagnet the electricity aligns the electrons.
Now back to the question. A magnet is using both gravity and magnetism, two separate forces. The gravity is acting on the magnet just like it is on any other object. In space time it is like placing it on a stretched piece of cloth, where as the depression in the cloth represents the force of attraction. Obviously this is menial in most cases as the size of anything here on earth has such a low gravitational force due to it's mass that we really can't see anything.
The magnetic force is much stronger. Due to electron alignment it is much stronger than gravity, and can 'override' it's effects.
In a thought experiment think if it this way. Place a bowling ball on a trampoline. This will cause a depression as such that if you placed a spherical magnet on the trampoline the magnet would simply roll to the center until it hits the bowling ball and stays there. This represents the force of gravity on the magnetic sphere in space time.
Now if we used another magnet to pull the original spherical magnet away from the bowling ball we would see magnetism 'overriding' the force of gravity.
I hope this helps.

Answer 2

All the forces act in similar manners. Physicists since Einstein have been attempting to describe a universal relation ship.
Magnetic fields react only with other magnetic fields it doesn't matter what causes them, so it is not magnets that act on each other it is the fields.

Answer 3

i'm confident you already is prevalent with this yet for in spite of it fairly is properly worth....unification could result from an extension of Machian dynamics. Julian Barbour has spent some years on the thought factor, as we become attentive to it, does no longer exist as something different than an phantasm. (i think it fairly is variety of how television and flicks artwork). Einstein only mandatory to pass slightly extra with relativity, possibly. besides, it form of sounds like he's transforming into further and extra "observed". And he says that if he can no longer unify the theories he will consume a malicious program! I made that final section up.
