What Is This Tool?
This converter translates magnetic field strength values from ampere turn per meter (At/m), an SI-based unit, into oersted (Oe), a cgs-emu unit. It helps bridge measurements used in electromagnet design and legacy magnetic field analyses.
How to Use This Tool?
- Enter the magnetic field strength value in ampere turn per meter (At/m)
- Select the target output unit as oersted (Oe)
- Click the convert button to get the corresponding value in Oe
- Review the results to apply in design, analysis, or comparison tasks
Key Features
- Supports conversion of magnetic field strength units: At/m to Oe
- Based on a precise conversion factor between SI and cgs-emu units
- Useful for comparing modern electromagnet data with older magnetic performance parameters
- Browser-based and easy to use without needing installation
Examples
- Convert 10 At/m: 10 × 0.0125663706 = 0.125663706 Oe
- Convert 50 At/m: 50 × 0.0125663706 = 0.62831853 Oe
Common Use Cases
- Determining magnetizing force in electromagnet and solenoid designs
- Analyzing magnetic circuits and transformer cores
- Evaluating permanent magnet characteristics reported in Oe
- Comparing measurements between SI and legacy cgs unit systems
- Interpreting old laboratory equipment and literature data
Tips & Best Practices
- Ensure you understand the context since At/m and Oe belong to different unit systems
- Use the conversion primarily for free-space or non-magnetic conditions
- Double-check conversions when analyzing materials with varying permeability
- Keep in mind that Oe usage is declining in favor of SI units
- Use the tool to support compatibility with older datasheets and research
Limitations
- Conversion accuracy assumes free-space or non-magnetic media conditions
- Material-specific permeability can influence actual magnetic field strength relations
- Units belong to different systems (SI vs cgs-emu), requiring careful interpretation
- The oersted unit is becoming less common in modern measurements and equipment
Frequently Asked Questions
- What does ampere turn per meter (At/m) measure?
- Ampere turn per meter measures the magnetizing force or magnetic field strength as the number of ampere-turns per unit length of a magnetic path.
- Why convert At/m to oersted (Oe)?
- Conversion is useful for comparing SI-based electromagnet data with legacy datasheets, magnetic hysteresis plots, and laboratory results that use the cgs-emu unit Oe.
- Is the conversion between At/m and Oe exact for all materials?
- No, the conversion applies mainly to free space or non-magnetic media; differences in material permeability can affect the relationship.
Key Terminology
- Ampere turn/meter [At/m]
- An SI unit measuring magnetizing force as the number of coil turns multiplied by current per meter length of magnetic path.
- Oersted [Oe]
- A cgs-emu unit quantifying magnetic field strength, used primarily in older datasheets and laboratory measurements.
- Magnetic field strength (H)
- A measure of magnetizing force, indicating the intensity of a magnetic field.
