Magnetomotive force per unit length is the definition of magnetic field strength (symbol: H), formerly known as 'magnetising force'.
Magnetomotive force is the product the the current flowing through a coil and the number of turns that make up that coil, and its SI unit of measurement is the ampere (although this is often spoken as 'ampere turn').
So, the SI unit of measurement of magnetic field strength is the ampere per metre, although, again, it is often spoken as 'ampere turn per metre'.

How do you calculate magnetic flux density?
'Magnetic field strength' (symbol: H) is defined as 'the magnetomotive force, per unit length, of a magnetic circuit'. In SI, it is expressed in amperes per metre (A/m), which is often spoken as "'ampere turns' per metre".It's equation is: H = (IN) / lwhere:H = magnetic field strength (ampere per metre)I = current flowing through coil (amperes)N = number of turns in coill = length of magnetic circuit
How can you Calculate the change in length of a steel bridge girder that will be exposed to a temperature change?
Use the coefficient of thermal expansion. This is a measure of how much a unit length of steel would expand per each unit increase in temperature. There are different kinds of steel so you may need to know its composition.
What is the kWh production per unit of geothermal energy?
50000 to 100000 Kw/ unit
What is the emu unit of permittivity expressed in Siemens per meter?
Do you mean conductivity?One emu unit of conductivity is 109 abmhos per cm, or 1011 S/m.
What is the unit to measure the strength of a magnetic field?
We can say magnetic field strength is a measure of magnetic strength of a magnet.. like electric field density in electrostatics.... ex consider a current carrying wire which produce a magnetic field in radial direction... by using ampere law.. we can easily find magnetic field strength at a point (r distance from wire)... H=I/(2*3.14*r).. its like finding a electric field intensity by Guass law.......The magnetic field ranges from less than 30 micro-teslas (0.3 gauss) to 60 microteslas (0.6 gauss) The strength varies daily usually about 25 nanoteslas (nT) with variations every second of 1 nTAnswerMagnetic field strength (symbol H) is defined as the magnetomotive force per unit length of a magnetic circuit, and is expressed in amperes per metre (A/m). The original answer appears to be defining flux density(expressed in teslas), not magnetic field strength.
What is the dimension of gravitation?
Gravitation can be expressed as either an acceleration or a force per unit mass.[Acceleration] = [Length/Time2][Force per unit mass] = [mass-length/Time2] per [mass] = [length/time2]
How do you calculate magnetic flux density?
'Magnetic field strength' (symbol: H) is defined as 'the magnetomotive force, per unit length, of a magnetic circuit'. In SI, it is expressed in amperes per metre (A/m), which is often spoken as "'ampere turns' per metre".It's equation is: H = (IN) / lwhere:H = magnetic field strength (ampere per metre)I = current flowing through coil (amperes)N = number of turns in coill = length of magnetic circuit
What is the formula for calculating magnetic field?

Magnetizing force is equal to magnetic force?
'Magnetic Force' (symbol: H), an obsolete term, which has been long replaced by the term, 'Magnetic Field Strength', is defined as the magnetomotive force per unit length of a magnetic circuit. It is measured in amperes per metre(A/m), although this is often spoken as 'ampere turns' per metre. And, no, it is not the same thing as 'magnetic force'.(If you compare a magnetic circuit with an electric circuit, then 'magnetomotive force' is equivalent to 'electromotive force' -and, continuing the analogy, magnetic field strength is equivalent to 'voltage gradient'.)Magnetomotive force is the product of the current flowing through a coil and its number of turns. It's unit is the ampere (A), but is often spoken as 'ampere turn'.So, by way of example, suppose we have a magnetic circuit comprising a steel toroid of circumference 100 mm (0.1 m), around which a coil of 200 turns is uniformly wound. If a current of 0.5 A passes through the coil, then the magnetic field strengthwill be:H = (I N) / circumference = (0.5 x 200) / 0.1 = 1000 A/m
What are the units of force constant?
A unit of force is the force that is exerted by gravity. The standard unit of forces is known as newton and is named after Isaac Newton.
Oz per in to N per m² How do you convert ounces per inch to newtons per meter squared?
You cannot.An ounce per inch is a measure of mass per unit length whereas newtons per metre is a measure of force per unit length. Since mass is not the same as force, there can be no conversion between the two measures.
What is stress Strain?
Stress is the amount of force per unit area (N/mm2; lb/ft2) Strain is the unitless change in length resulting from the application of a force (movement in unit length / original unit length) Young's Modulus relates the two (stress / strain)
Fundamental unit of young's modulus of elasticy?
Pressure (Pa) is force per area (N/m^2). Force is (Mass*Length)/Time^2, so force per area is Mass/(Length*Time^2).
Amount of force exerted per unit?
Per what kind of unit? A common unit is pressure: force per unit area.
What is the unit of force that expresses force?
(Any unit of mass) times (any unit of length or distance) divided by (the square of any unit of time)makes a unit of force.In the metric system, the standard unit is the newton, defined as one kilogram-meter per second2 .
Why the units of stress and pressure are same?
Because they both involve force acting per unit area/length
What is the amount of force appplied per unit of area?
Pressure is defined as force per unit area.
