Non-linear magnetic materials may require additional analysis beyond this unit conversion
Frequently Asked Questions
-
Are ampere turn per meter and ampere per meter the same unit?
-
Yes, At/m and A/m are numerically equivalent in the SI system, both representing magnetic field strength.
-
When should I use ampere turn per meter instead of ampere per meter?
-
Use At/m to specify magnetizing force involving coil turns explicitly, especially in electromagnet or solenoid designs.
-
Does this conversion apply to non-linear magnetic materials?
-
This conversion assumes linear media behavior; additional considerations are needed for non-linear magnetic materials.
Key Terminology
-
Ampere turn per meter [At/m]
-
A magnetic field strength unit measuring magnetizing force as coil turns multiplied by current per unit magnetic path length.
-
Ampere per meter [A/m]
-
The SI unit of magnetic field strength, quantifying the magnetizing field generated by electric currents or magnetized materials.
-
Magnetizing force (H)
-
A measure of magnetic field intensity produced by current in coils, calculated as the product of turns and current divided by magnetic path length.
