# Magnetisation is a dynamical situation of moving charges

• pivoxa15
In summary, there is a debate about whether magnetism should be studied on its own or at a more fundamental level involving the properties of moving charges. While magnetism can be described by a single theory, it is not the same as statics and can involve other factors such as individual spins of particles.

It is established that magnetisation is a dynamical situation of moving charges. Hence it is not an independent phenomena. But why keep on studying magnetics by itself? For example, search for magnetic monopoles, magnetisation of objects? Shouldn't we study it at a fundalmental level using properties of charges when in motion instead?

But we do study magnetism at it's most fundamental level. That being the level of atoms and electrons and their interactions in condensed matter. Your question is a bit unclear to me and maybe I'm missing your point?

maxwell proved that magnetics and statics are the same, therfor the op asks why do we separate the two in some courses, when we could just learn electromagnetics.

That doesn't make any sense either.

While they can be described by a consistent, single theory, they are not "the same". That's like asking why can we just study "acceleration" rather than force since they're "the same"?

Note that not ALL magnetism are generated by "moving charges". As inha as mentioned, the study of magnetism, especially in condensed matter does not involved moving charges. Individual spins of particles are not due to such a thing. You simply cannot transform such a description away and deal instead with moving charges.

## What is magnetisation?

Magnetisation is the process by which a material becomes magnetized, meaning it acquires a magnetic field. This can occur when the material is placed in a magnetic field or when the material is made up of atoms with inherent magnetic properties.

## What is a dynamical situation?

A dynamical situation refers to a state in which there is movement or change over time. In the case of magnetisation, it means that the charges within the material are in motion, creating a magnetic field.

## What are moving charges?

Moving charges refer to particles, such as electrons, that are in motion within a material. These particles have an electric charge and their movement can create a magnetic field, leading to magnetisation.

## How does magnetisation occur?

Magnetisation occurs when the magnetic moments of the particles within a material align in a specific direction, either due to an external magnetic field or due to the inherent magnetic properties of the material. This alignment of magnetic moments creates a net magnetic field for the material.

## What are the practical applications of magnetisation?

Magnetisation has many practical applications, including in the production of magnets, electric motors, and generators. It is also used in technologies such as MRI machines, speakers, and magnetic data storage devices. Magnetisation is also important in understanding the behavior of materials in Earth's magnetic field and in the study of electromagnetism.
