STEP 0: Pre-Calculation Summary

Formula Used

Mutual Inductance = ([Permeability-vacuum]*Relative Permeability*Area of Coil*Number of Conductors*Secondary Turns of Coil)/Mean Length
M = ([Permeability-vacuum]*μ_r*A*Z*N₂)/L_mean
This formula uses 1 Constants, 6 Variables

Constants Used

[Permeability-vacuum] - Permeability of vacuum Value Taken As 1.2566E-6

Variables Used

Mutual Inductance - (Measured in Henry) - The Mutual Inductance is defined as when two or more coils are magnetically linked together by a common magnetic flux.
Relative Permeability - (Measured in Henry per Meter) - Relative Permeability is the ratio of effective permeability of a particular fluid at a particular saturation to absolute permeability of that fluid at total saturation.
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.
Number of Conductors - Number of Conductors is defined as the total number of conductors present at the armature winding of any machine.
Secondary Turns of Coil - Secondary turns of coil is number of turns of 2nd winding or number of turns of secondary winding of transformer.
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.

What is mutual and self-inductance?

Mutual inductance is simply the generation of an induced EMF in a coil as a result of current flowing in an adjacent coil. In self-inductance, changes in the flow of current in a coil are opposed by the coil itself by inducing an EMF in the same coil, i.e., no other coil is involved.

What is this inductance?

inductance, property of a conductor (often in the shape of a coil) that is measured by the size of the electromotive force, or voltage, induced in it, compared with the rate of change of the electric current that produces the voltage.

How to Calculate Mutual Inductance?

Mutual Inductance calculator uses Mutual Inductance = ([Permeability-vacuum]*Relative Permeability*Area of Coil*Number of Conductors*Secondary Turns of Coil)/Mean Length to calculate the Mutual Inductance, Mutual inductance out of the two coils one coil opposes change in the strength of the current flowing in the other coil. Mutual Inductance is denoted by M symbol.

How to calculate Mutual Inductance using this online calculator? To use this online calculator for Mutual Inductance, enter Relative Permeability (μ_r), Area of Coil (A), Number of Conductors (Z), Secondary Turns of Coil (N₂) & Mean Length (L_mean) and hit the calculate button. Here is how the Mutual Inductance calculation can be explained with given input values -> 0.746128 = ([Permeability-vacuum]*1.9*0.25*1500*18)/0.0216.

FAQ

What is Mutual Inductance?

Mutual inductance out of the two coils one coil opposes change in the strength of the current flowing in the other coil and is represented as M = ([Permeability-vacuum]*μ_r*A*Z*N₂)/L_mean or Mutual Inductance = ([Permeability-vacuum]*Relative Permeability*Area of Coil*Number of Conductors*Secondary Turns of Coil)/Mean Length. Relative Permeability is the ratio of effective permeability of a particular fluid at a particular saturation to absolute permeability of that fluid at total saturation, 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, Number of Conductors is defined as the total number of conductors present at the armature winding of any machine, Secondary turns of coil is number of turns of 2nd winding or number of turns of secondary winding of transformer & The Mean length the effective length of a closed magnetic loop inside a magnetic core made of ferromagnetic material which may be also gapped.
