Reluctance Solution

STEP 0: Pre-Calculation Summary
Formula Used
Reluctance = Mean Length/(Magnetic Permeability of a Medium*Area of Coil)
S = Lmean/(μ*A)
This formula uses 4 Variables
Variables Used
Reluctance - (Measured in Ampere-Turn per Weber) - The reluctance of a magnetic material is its ability to oppose the flow of magnetic flux. The magnetic flux created by the field windings follows the path of least magnetic reluctance.
Mean Length - (Measured in Meter) - The Mean length the effective length of a closed magnetic loop inside a magnetic core made of ferromagnetic material which may be also gapped.
Magnetic Permeability of a Medium - (Measured in Henry per Meter) - Magnetic Permeability of a medium is the measure of magnetization that a material obtains in response to an applied magnetic field.
Area of Coil - (Measured in Square Meter) - The area of coil is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.

What is the symbol of reluctance?

The symbol for reluctance is S (or Rm). The unit of reluctance is 1/H (or H-1) or At/Wb.
Reluctance(S) is the property of a magnetic circuit opposing the passage of magnetic flux lines, equal to the ratio of the magnetomotive force to the magnetic flux. MMF = Reluctance × flux. NI = Sϕ ⇒ S = N I ϕ

What is the unit for flux?

The SI unit of magnetic flux is the Weber (Wb). A flux density of one Wb/m2 (one Weber per square metre) is one Tesla (T). Weber is commonly expressed in a multitude of other units.

How to Calculate Reluctance?

Reluctance calculator uses Reluctance = Mean Length/(Magnetic Permeability of a Medium*Area of Coil) to calculate the Reluctance, Reluctance (also known as reluctance, magnetic resistance, or a magnetic insulator) is defined as the opposition offered by a magnetic circuit to the production of magnetic flux. It is the property of the material that opposes the creation of magnetic flux in a magnetic circuit. Reluctance is denoted by S symbol.

How to calculate Reluctance using this online calculator? To use this online calculator for Reluctance, enter Mean Length (Lmean), Magnetic Permeability of a Medium (μ) & Area of Coil (A) and hit the calculate button. Here is how the Reluctance calculation can be explained with given input values -> 0.617143 = 0.0216/(0.14*0.25).

FAQ

What is Reluctance?
Reluctance (also known as reluctance, magnetic resistance, or a magnetic insulator) is defined as the opposition offered by a magnetic circuit to the production of magnetic flux. It is the property of the material that opposes the creation of magnetic flux in a magnetic circuit and is represented as S = Lmean/(μ*A) or Reluctance = Mean Length/(Magnetic Permeability of a Medium*Area of Coil). The Mean length the effective length of a closed magnetic loop inside a magnetic core made of ferromagnetic material which may be also gapped, Magnetic Permeability of a medium is the measure of magnetization that a material obtains in response to an applied magnetic field & The area of coil is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.
How to calculate Reluctance?
Reluctance (also known as reluctance, magnetic resistance, or a magnetic insulator) is defined as the opposition offered by a magnetic circuit to the production of magnetic flux. It is the property of the material that opposes the creation of magnetic flux in a magnetic circuit is calculated using Reluctance = Mean Length/(Magnetic Permeability of a Medium*Area of Coil). To calculate Reluctance, you need Mean Length (Lmean), Magnetic Permeability of a Medium (μ) & Area of Coil (A).
