What is magnetism? does relativity theory expalin it?Or string theory?

Question

Electron death?

Answer 1

Magnetism is explained by relativity.

Magnetism is really another manifestation of the electric force. When there is motion, relativity says length contracts. The contraction of length changes the density of charged particles.

Suppose you have a wire with a current moving through it. Then you put a charged object next to the wire. The density of positive charges is the same as the density of negative charges in the wire, so there is no electric field. When you move the charged object, relativity says the distances contract. So now the densities of positive and negative charges in the wire change, and they change by different amounts because the negative charges are in motion relative to the positive charges. This imbalance creates an electric field, which acts on the charged object in motion. This is the magnetic force, which is really an electric force.

Answer 2

In physics, magnetism is a phenomenon by which materials exert an attractive or repulsive force on other materials. Some well known materials that exhibit easily detectable magnetic properties are iron, some steels, and the mineral lodestone; however, all materials are influenced to one degree or another by the presence of a magnetic field, although in most cases the influence is too small to detect without special equipment.

Relativity and String theory are not related to topics in magnetism as far as i know

Answer 3

In physics, magnetism is one of the phenomena by which materials exert an attractive or repulsive force on other materials. Some well known materials that exhibit easily detectable magnetic properties are iron, some steels, and the mineral lodestone; however, all materials are influenced to greater or lesser degree by the presence of a magnetic field.


String theory is at the moment the most promising candidate for a unified description of the
fundamantal particles and forces in nature including gravity. In string theory the myriad of
particles types is replaced by a single fundamental building block, a string. The string can
vibrate and different vibration modes of the string represent the different paricle types. One
such vibration represents the graviton the particle carrying the force of gravity. One can
study the interaction of gravitons in string theory, which can not be done in any other way.
So string theory (or more exactly superstring theory) resolves one of the most enigmatic
problems of the twentieth century theoretical physics: how to reconcile between quantum
mechanics and general relativity.


General relativity was developed by Einstein in the years 1907 - 1915. General relativity replaces the global Lorentz symmetry of special relativity with a local Lorentz symmetry in the presence of matter. The presence of matter "curves" spacetime, and this curvature affects the path of free particles (and even the path of light). General relativity uses the mathematics of differential geometry and tensors in order to describe gravitation as an effect of the geometry of spacetime. This theory is based on the general principle of relativity, which requires all observers to experience the same laws of physics, not just those moving with uniform speed, hence its name.

So in answer to your question - - magnetism does not EXPLAIN relativity theory or string theory - but magnetism can be involved.

Answer 4

unphyical act of attracting something of physical body magnetism is actual an act of electricity.

example; LODESTONE b : a body having the property of attracting iron the (unphyical act of attracting something of physical body). Ex. A lodestone has the property of attracting iron, some steel, or some alloy. While the lodestone is physical the attraction is not physical but is best described as having the property of attractin iron. Various other objects alos have small degree of magnetism when outside influence is applied. (such as electrical fields)

Magnetism is also a property that can be produced, You can produce magnetism by rubbing silk, rubbing a stroform cup against your hand and than remove small peioces of it and watch it stick to your hand. Having worked in electricity for years I do know the human body can show a small amount of magnetism after working hot circuits. Small dust or sheds of metal or othe ritems may stick to you especiallyy if you are sweating a lot.
Due to the tremendous influence of the world's oil producing countries, oil companies, and distributers/investors this science is seriousous undeveloped or researched.

Answer 5

Magnetism is caused by the degradation of electrons orbits as they sprial in toward the nucleus of the atom.
