How dose `Magnetism work?

Answer 1

Magnetism is a force which manifests itself through virtue of the fact that the electric interation is so much stronger than the gravitational one.

Relativity shows that when objects move, the properties of space and time alter. Normally, this is not noticable. However, electro static forces are so much stronger than other everyday forces that when charged particles move, they can influence space in ways that normal stuff only could if it was travelling at almost the speed of light.

The effect of this is that moving charges [currents] can impose strange field effects as they move. This is magnetism. Magnetism is simply an effect of relativity. The reason we notice is simply because the Electric forces are much greater than gravitational forces we experience.

[if you doubt this, think that the gravitational of the earth on a balloon can be completely counteracted by rubbing the balloon on your hair. The electro static force of a few thousand electrons can pin a balloon to a wall despite the whole Earth trying to pull it down.

Answer 2

Hi,
Any current carrying conducter has a magenetic field sorrounding it.
When electrons orbit round the atom, they may be considered as moving current, ie an a charge moving is electricity.This produces a magnetic field for each single electron The cummulative effect produced by the million of electrons adds up to produce a significant magnetic effect. While magnetising a bar, the electrons are in essence being aligned to rotate in an organised way that produces magnetism that adds up on one another rather than cancelling each others effect. This way the net effect is a quantity of magnetism that is significanct

Answer 3

Scientists don't fully know. Only that it's there and moving an iron core within a magnetic field produces electric.

I've often wondered if magnetism is only due to specific types of atom? Is it a ripple effect or a flow of particles? Is the current theory of atoms wrong which prevents us from understanding magnetism?

Answer 4

Magnetism is borne out of an interaction between a mass stucture and space structure. The result of the interaction is a formation of space configuration. This type of configuration stores power in the form of a force called magnetism.
In atomics structure it is the electron spin that involves this interaction. So the type of motion of the electron results in a moving magnetic field.So in order to have magnetism both the electron and the field is in motion.So the magnetic flux is a function of time and has the dimension of time called the second.
The 'B'field is the magnetic density and has the dimensions seconds per meter square.

So Magnetic field is related to time and therefore are equivalent.

Answer 5

it depends but with some metals that are naturally magnetic they give and take positive and negative elcetrons and because of the north and south poles they can interfeer with magnatism

just like in world war 2 when a big ship was passing by it would disrupt the earths magnetic flow and the germans used magnetic mines to blow them up :(

but magnatism can be produced in different ways such as ELECTRO MAGNATISM which is a soft iron core wrapped in a metal wire and with a current running through that wire it can make that soft iron magnetic....

Answer 6

magnetism does nt work it is , the earth has a molten iron core which has a magnetic field eminating from its axises , north & south poles . if it worked we could shut it off & on , we cant . therefore it is a natural force , we use it to produce electricity another natural force which we strive to control through insolated wiring circuits this knowlege has lead us to where we are today computers ect . if ever magnetism ceased to exist we could no longer produce electricity , they are brothers in arms , hope this helps no one really understands these forces they just are .

Answer 7

Wikipedia explains it here:

Alternatively the "parody of Wikipedia" site fails to explain it sensibly here:

Answer 8

opposites attract.

one end of the magnet is positive, teh other negative...
