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
What is pressure equal to?
Pressure is equal to force per unit area. It is calculated by dividing the force applied to an object by the area over which the force is distributed. This relationship is described by the formula P = F/A, where P is pressure, F is force, and A is area.
What is the result of a force distributed over an area?
When a force is distributed over an area, it results in pressure. Pressure is the force per unit area and is calculated as the force divided by the area over which it is applied. This pressure can have different effects depending on the surface and the material being acted upon.
What does PSI mean in air pressure?
PSI stands for pounds per square inch, which is a common unit of measurement for air pressure. It represents the amount of force exerted by the air on a given area. It is commonly used to measure tire pressure in vehicles.
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 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]
Which Quantity has unit Newton per meter?
The quantity that has the unit Newton per meter is force per unit length, which represents the concept of tension or linear force distribution along a line.
What is the formula for calculating magnetic field?
'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 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)
Why the dimension of surface tension is MLT-2?
The dimension of surface tension is MLT-2 because it is defined as the force acting perpendicular to a unit length of interface between two fluids. The force per unit length has units of force/length, which can be expressed as MLT-2.
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).
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
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 is spring constant of an elastic material?
The spring constant of an elastic material is a measure of how stiff the material is. It represents the force required to stretch or compress the material by a certain amount. It is typically denoted by the symbol k and has units of force per unit length or force per unit deformation.
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 .
