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.

what caused a nail to be given with magnetic property
- Magnetic field strength is the intensity of a magnetic field at a given location. Historically, a distinction is made between magnetic field strength H, measured in ampere/meter, and magnetic flux density B, measured in tesla. Magnetic field strength is defined as the mechanical force (newton) on a wire of unit length (m) with unit electric current(A). The unit of the magnetic field, therefore, is newton/ (ampere x meter), which is called tesla. The magnetic field may be visualized by magnetic field lines. The field strength then corresponds to the density of the field lines. The total number of magnetic field lines penetrating an area is called magnetic flux. The unit of the magnetic flux is tesla x m2 = weber. The older units for the magnetic flux, maxwell = 10-8 weber, and for the magnetic flux density, gauss = maxwell / cm2 = 10-4 tesla, are not to be used any more. Magnetic flux density diminishes with increasing distance from a straight current-carrying wire or a straight line connecting a pair of magnetic poles around which the magnetic field is stable. At a given location in the vicinity of a current-carrying wire, the magnetic flux density is directly proportional to the current in amperes. If a ferromagnetic object such as a piece of iron is brought into a magnetic field, the "magnetic force" exerted on that object is directly proportional to the gradient of the magnetic field strength where the object is located. ------------------------------------------------------------------- B=μH Magnetic field in Solenoid B=μnI where n is turns/m So H=nI --------------------------------------------
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.

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.
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
magnetic variation
Density is mass per volume. Take the volume and multiply it by the density. Make sure the units used are the same.
