What Is This Tool?

This converter transforms values of magnetomotive force from ampere turn (At), the SI unit representing magnetic potential in coils, into gilbert (Gi), the older CGS-EMU unit used in legacy magnetic circuit analyses.

How to Use This Tool?

  • Enter the magnetomotive force value in ampere turns (At).
  • Select ampere turn as the input unit and gilbert as the output unit.
  • Click the convert button to get the equivalent value in gilberts (Gi).
  • Use the converted value to analyze magnetic circuits or interpret historical data.
  • Refer to the provided examples for guidance on using the conversion.

Key Features

  • Converts magnetomotive force from ampere turn to gilbert accurately based on the established conversion rate.
  • Facilitates understanding and comparison between SI and CGS electromagnetic units.
  • Supports applications in transformer, electric machine, relay, and inductor design.
  • Useful for interpreting and converting legacy data from historical electromagnetic literature.
  • Provides clear examples of conversion to assist users.

Examples

  • 5 ampere turns equal 6.28318531 gilberts after conversion using the factor 1.256637062.
  • 10 ampere turns convert to 12.56637062 gilberts using the same conversion rate.

Common Use Cases

  • Determining required coil winding specifications (turns × current) for desired magnetic flux.
  • Calculating magnetizing forces in transformer and electric machine core designs.
  • Sizing relays, inductors, or magnetic circuits for target core flux densities.
  • Converting legacy electromagnetic data from CGS units to SI units for modern analysis.
  • Reporting magnetomotive force in older standards and electromagnetic literature.

Tips & Best Practices

  • Always verify unit selection before conversion to avoid errors.
  • Use this tool for linear magnetic conditions; apply corrections if nonlinearity or saturation occur.
  • Cross-check converted values when working with legacy data to ensure accurate interpretation.
  • Refer to examples to confirm correct usage of the conversion factor.
  • Be aware that gilbert is less common in modern applications, so validate units in your context.

Limitations

  • Conversion presumes ideal magnetic conditions without saturation or nonlinearity effects.
  • Gilbert unit is outdated and less prevalent in current engineering, requiring careful validation.
  • Real-world magnetic circuits may need additional factors not accounted for by this simple conversion.

Frequently Asked Questions

What does the ampere turn (At) unit represent?
Ampere turn represents magnetomotive force equal to the product of electric current and the number of coil turns, indicating magnetic driving potential in a circuit.

Why convert ampere turn to gilbert?
Converting to gilbert allows comparison with older CGS-based measurements and historical electromagnetic data for consistent analysis.

Can this conversion be used in nonlinear magnetic materials?
No, conversions assume ideal linear magnetic conditions; real nonlinear effects require more complex adjustments.

Key Terminology

Ampere turn (At)
A unit of magnetomotive force representing the product of current in amperes and coil turns; quantifies magnetic potential driving magnetic flux.
Gilbert (Gi)
An older CGS-EMU unit of magnetomotive force named after William Gilbert, used in legacy magnetic circuit analysis.
Magnetomotive force (MMF)
The magnetic driving force generated by electric current in coils, analogous to electromotive force in electric circuits.
