What Is This Tool?
This converter transforms magnetic field strength measurements from oersted (Oe), a cgs-emu unit representing magnetizing force, into ampere turn per meter (At/m), an SI-related unit measuring magnetizing force in terms of coil turns and current per length.
How to Use This Tool?
- Enter the value in oersted (Oe) you want to convert.
- Select ampere turn per meter (At/m) as the target unit.
- Click the convert button to see the equivalent magnetizing force in At/m.
- Use the result in engineering or research calculations involving magnetic fields.
Key Features
- Converts values between oersted and ampere turn/meter with provided conversion rate.
- Supports translating older magnetic measurement data into SI-compatible units.
- Includes practical examples illustrating the conversion process.
- Browser-based and easy to use without additional software.
- Useful for engineers and researchers working with magnetic field strength.
Examples
- 2 Oe converts to approximately 159.1549 At/m by multiplying 2 × 79.5774715459.
- 0.5 Oe converts to about 39.7887 At/m by multiplying 0.5 × 79.5774715459.
Common Use Cases
- Specifying coercive field values and magnetic parameters from older datasheets.
- Plotting magnetic hysteresis loops with H in Oe and B or M in gauss or emu.
- Converting legacy magnetic data for modern SI-based analysis and design.
- Designing electromagnets and solenoids by determining magnetizing force.
- Analyzing magnetic circuits and transformer cores using magnetomotive force per length.
Tips & Best Practices
- Verify that the magnetic context is appropriate for cgs-to-SI conversion (usually free space or non-magnetic materials).
- Use this tool to compare and translate older experimental data with current standards.
- Account for possible nonlinearity or field non-uniformity when applying At/m in complex materials.
- Cross-check converted values with your specific engineering requirements for accurate application.
Limitations
- Oersted unit is mainly valid in free space or materials without magnetic complexity; conversion may be less accurate otherwise.
- Ampere turn per meter assumes linearity and uniform magnetic fields, which might not be true in practical magnetic circuits.
- This tool does not factor in magnetic permeability variations or detailed experimental conditions.
Frequently Asked Questions
- What is the oersted unit used for?
- Oersted measures magnetic field strength, especially the magnetizing force applied to materials, commonly seen in older magnetic literature and equipment.
- How is ampere turn per meter defined?
- Ampere turn per meter quantifies magnetizing force as the number of coil turns times current per length, numerically matching amperes per meter in the SI system.
- Why convert oersted to ampere turn per meter?
- Converting to ampere turn per meter allows use of magnetic field strength values in SI-based engineering applications like electromagnet design and magnetic circuit analysis.
Key Terminology
- Oersted (Oe)
- A cgs-emu unit of magnetic field strength representing the magnetizing force, primarily used in older magnetic data.
- Ampere turn per meter (At/m)
- An SI-related unit of magnetizing force defined as coil turns multiplied by current divided by magnetic path length, numerically equivalent to A/m.
- Magnetizing Force (H)
- The magnetic field strength that causes magnetic materials to become magnetized, measured in Oe or At/m.
