Magnetometer Dipole Strength nT Tool
Ideal point dipole AXIAL field inversion B=μm/(2πr³), signed moment retained; not buried source identity, off axis estimate or geomagnetic background inference. Caller independently establishes sample/context/calibration applicability; not definitive chronology, provenance, taxonomy, disease or human identity.
Description
An axial dipole model connects field strength, distance and medium permeability.
An axial dipole model connects field strength, distance and medium permeability.1
Its inferred moment does not establish the source geometry or replace magnetic inversion. Use Magnetometer Dipole Strength nT Tool to evaluate the supplied inputs under the model explained below.
When to use Magnetometer Dipole Strength nT Tool
Use Magnetometer Dipole Strength nT Tool to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Magnetometer Dipole Strength nT Tool and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Observed axial field nt, Independent axial distance meters, Caller medium permeability henry per meter using the field table and validation rules below, then run the tool.
- Read Ideal axial dipole moment ampere m2; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedAxialFieldNt | Observed axial field nt | number | Required; constraints below |
| independentAxialDistanceMeters | Independent axial distance meters | number | Required; constraints below |
| callerMediumPermeabilityHenryPerMeter | Caller medium permeability henry per meter | number | Required; constraints below |
Enter a finite signed axial field in nT, positive independently matched axial distance in m and positive permeability in H/m. Convert nT to T and compute B×2π×r³/permeability for A·m². A negative field returns a negative model moment. No source-location estimation or nonaxial correction occurs.

}Limitations and assumptions
Its inferred moment does not establish the source geometry or replace magnetic inversion. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
