It is Johann Carl Friedrich Gauss whose name (Gauss) we apply to the CGS unit of measure of magnetic flux density. Wikipedia has a post on the Gauss (the unit of measure), and they also have a post on Carl Friedrich Gauss, too. Links are provided. To read more about Gauss on the Answers.com website, use that related link.
Volume density refers to the amount of mass present in a given volume of a substance, while magnetism is a property that allows an object to exert a force on other objects without physically touching them. Materials with higher volume density have more mass packed into a specific volume, while magnetic materials have domains of aligned magnetic moments that produce a magnetic field.
Something that which produces a magnetic fieldThe magnetic field that surrounds a magnet is made up of magnetic flux (symbol, the Greek letter 'phi'), usually represented as lines in field diagrams. The SI unit for measuring magnetic flux is the weber (pronounced 'vay-ber'). The intensity of this flux (the closeness of the lines in diagrams) is called the flux density (symbol: B). Flux density is greatest in the areas nearest a magnet's poles. Flux Density is defined as 'flux per unit area', and is measured in webers per square metre which, in SI, is given the special name, the 'tesla'.
With constant number of windings and current, the magnetic field density of a solenoid remains constant. However, magnetic flux is determined by the flow of magnetic field force through a given area. Therefore, the area is linearly and directly proportional to the magnetic flux.
Strictly speaking if the density is given then you don't need to find it.

The answer depends on the units in which the mass and density are given.
The formula for calculating power if you are given a magnetic field is sub 43
A uniform magnetic field is a magnetic field that has the same strength and direction at all points in a given region of space. It has constant magnetic flux density and does not vary in magnitude or direction within the specified area. Uniform magnetic fields are often used in scientific experiments and applications to provide consistent and predictable conditions for studying magnetic effects.
magnetic variation
Your question is unclear, but flux density is a function of the cross-sectional area of the magnetic circuit in which the magnetic flux is established.Flux density (symbol: B) is defined as 'the flux per unit area'. If the flux is measured in webers (pronounced 'vay-bers') and the cross-sectional area is measured in square metres, then the flux density is measured in teslas(symbol: T) which is a special name given to a weber per square metre.
