is magnetic repulsion and attraction is due to the bending of curvature of spacetime?
thank you for replying. I saw on internet that magnetic lines are curved due to the bending of space time.mrnike992 said:No. The bending curvature of spacetime causes gravitational attractive forces. The force of magnetic attraction and repulsion is attributed to one of the other four fundamental forces, the electromagnetic force.
Prashan Shan said:magnetic lines are curved due to the bending of space time.
then, can a strong enough magnetic field bent space time?PeterDonis said:This is true, but it's not what produces magnetic forces. Magnetic forces are present even where the curvature of spacetime is negligible.

mrnike992 said:Not directly, no.
ho much energy is required to bend space over a very small area.PeterDonis said:Actually, yes, it can. Magnetic fields contain energy, and energy produces spacetime curvature. But "strong enough" turns out to be very, very, very strong indeed; to produce the same spacetime curvature as the mass of the Earth does, you would need a magnetic field of about 10 million Tesla throughout an entire volume of space equal to the Earth's volume.

i asked this question because,,PeterDonis said:It's spacetime, not space, and how much energy is required depends on how much you want to bend spacetime, and over how small an area. In general it takes a lot of energy to cause measurable spacetime curvature; that's why we associate spacetime curvature, i.e., gravity, with large masses, since rest mass is the most concentrated form of energy we know. But even then, as you can see, it takes a lot of mass--the size of a planet--to produce significant spacetime curvature.
Prashan Shan said:what if space time is really bent when one magnetic field crosses another magnetic field.
The fundamental cause of magnetic repulsion and attraction is the presence of magnetic fields. These fields are produced by moving electric charges, such as the electrons in atoms and molecules. When two magnets are brought close together, their magnetic fields interact and result in either attraction or repulsion depending on the orientation of their poles.
Magnetic fields interact with each other through a force called the Lorentz force. This force is created when two magnetic fields are not parallel to each other, causing a push or pull between the two objects. The strength of this force depends on the strength of the magnetic fields and the distance between them.
The strength of magnetic repulsion and attraction is determined by the strength of the magnetic fields and the distance between the two objects. The closer the objects are, the stronger the force will be. Additionally, the strength of the magnetic fields can be affected by factors such as the material of the objects and their shape.
Magnets have different poles because of the arrangement of their electrons. Electrons have a property called spin, which creates a tiny magnetic field. In most materials, the electrons are arranged in pairs with opposite spin, canceling out their magnetic fields. However, in magnets, the electrons are aligned in the same direction, creating a stronger magnetic field and resulting in two poles: north and south.
No, magnetic repulsion and attraction cannot be completely explained by classical physics. Classical physics does not take into account the behavior of subatomic particles, such as electrons, which are responsible for creating magnetic fields. The behavior of these particles can only be explained by quantum mechanics, which is a more accurate and comprehensive theory of physics.
