Define as regardad the electro magnetic, magnetic field, Flux, Flux density and field density?

Electromagnetic field: An electromagnetic field is a physical field produced by electrically charged objects. It consists of both electric and magnetic components and is responsible for the interactions between charged particles.

Magnetic field: A magnetic field is a region in space where magnetic forces are present. It is produced by moving electric charges and magnetic materials and is responsible for the attraction or repulsion of magnetic objects.

Flux: Flux is a measure of the flow of a physical quantity through a surface. In the context of electromagnetic fields, flux refers to the amount of electric or magnetic field passing through a given area.

Flux density: Flux density is a measure of the amount of flux passing through a unit area. In the context of magnetic fields, flux density is often referred to as magnetic field strength and is measured in units of tesla (T) or gauss (G).

Field density: Field density is a measure of the strength of an electromagnetic field at a given point in space. It is a measure of the intensity of the electric or magnetic field at that point and is often used to describe the distribution of field strength in a given region.
