Oersted which is equal to 79.58 Am-1
AnswerAn oersted is an obsolete (cgsA) unit of measurement for flux density, not magnetic field strength. The SI unit is the ampere per metre.
Tesla
The unit of magnetism are: Weber for magnetic flux, Tesla for magnetic flux density and ampere per meter for magnetic field strength.
- 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 --------------------------------------------
A derived SI unit is made up of two or more SI base units. There are dozens of them. Pressure, volume, area, force, acceleration, velocity, energy, torque, momentum, power, temperature, electric and magnetic field, electric and magnetic flux, capacitance, inductance, eclectic potential, resistance, pressure, density, molar mass, and frequency are all derived SI values.
A football field is measuredin yards generally and the most common SI convertion is simply the international yard witch is only slight different.
There is none. Fahrenheit is not an SI unit.
the unit of magnetic field is tesla (si unit ) and gauss (cgs ) unit.1 tesla = 10,000 gauss .1 tesla= 1N/mAAnswerIt depends on what you mean by 'magnetic field'. If you mean 'magnetic flux', then the SI unit is the weber(pronounced 'vay-ber'). If you mean 'magnetic flux density', then the SI unit is the tesla. If you mean 'magnetic field strength', then the SI unit is the ampere per metre.
"Magnetic flux density" is also known as the magnetic field,The SI unit for this is the Tesla, written as T.CommentMagnetic flux density is not "also known as the magnetic field". It describes the intensity of a magnetic field.
Different units are used. From Wikipedia: "The term [magnetic field] is used for two distinct but closely related fields denoted by the symbols B and H, where H is measured in units of amperes per meter ... B is measured in teslas (symbol:T) and newtons per meter per ampere(symbol: N·m−1·A−1 or N/(m·A)) in the SI. ..."
Both units are used to measure magnetic flux density. The tesla is the SI unit of measurement, whereas the gauss is an obsolete, cgsA, unit.
The SI unit of attractive flux is the weber (Wb). The CGS unit is the maxwell.
The SI unit of magnetic flux is the weber (in derived units: volt-seconds)
The SI unit for force is the newton, N = kg m s-2. Magnetic field strength is measured in tesla, T = V s m-2 (or N A-1 m-1, or kg A-1 s-2, etc.). The strength of Earth's magnetic field is about 3 x 10-5 T.
The SI unit tesla (T) for measuring magnetic flux density or magnetic induction (commonly known as the magnetic field ) was named in Tesla¹s honour at the Conférence Générale des Poids et Mesures, Paris in 1960.
the strength of a magnetic field
In the position where the dirction of the magnetic field is perpendicular (normal) to the unit area.
The unit of magnetism are: Weber for magnetic flux, Tesla for magnetic flux density and ampere per meter for magnetic field strength.
Flux density is the number of magnetic lines crossing per unit area in perpeendicular direction. It is named as manetic field induction, B. Unit is tesla or weber/m2 Unit for magnetic flux is weber in SI system. Fl
