What Does North Indicate in Magnets?

[JPC]

hey ; with magnets we use North and South

but for example : what does north stands for ; indicate ?

i mean, if u have for example a magnetised material
lets say u got it magnetised by rubbing it with an other
if the material has more positive charges than negative : do we say its a Norh or South ?

To put my question more general :
does North attract positive charges or negative charges ?

North and south in magnets is just and old convention, coming from the time when people thought that there where magnetic charges (monopoles). You call north the side of a magnet which is attracted by the magnetic pole of the Earth north. And south the other one.

This has nothing to do with electric charges. Immobile electric charges are not attracted magnetic fields. But moving electric charges are deviated by magnetic fields.

I can provide a response to your questions about North in magnets. First, North and South are the two poles of a magnet. The North pole is typically labeled with a capital N and the South pole with a capital S. These poles are important because they determine how magnets interact with each other and with other materials.

In terms of what North stands for or indicates, it represents one of the poles of a magnet, specifically the end that points towards the Earth's geographic North pole. This is because Earth's magnetic field is aligned with its geographic axis, creating a North and South pole for the Earth's magnetic field.

In terms of your example of a magnetized material, the North pole of the magnet will always have a surplus of positive charges, while the South pole will have a surplus of negative charges. This is because opposite charges attract, so the North pole of a magnet will attract the South pole of another magnet.

To answer your more general question, North does not necessarily attract positive or negative charges on its own. Instead, it is the interaction between the North and South poles of magnets that creates the attraction or repulsion between them. In other words, the North pole of one magnet will attract the South pole of another magnet, regardless of whether they have positive or negative charges.

In conclusion, North in magnets refers to one of the poles of a magnet and indicates the direction of the Earth's magnetic field. It also plays a key role in determining how magnets interact with each other and with other materials.
