Field Strength Converter
Ampere/meter (A/m)
Definition: Ampere per meter is the SI unit of magnetic field strength. It represents the magnetic field produced by a current of one ampere flowing through a straight conductor of infinite length.
History/origin: Established as part of the metric system standardization to create a direct link between electrical current and the magnetic force it generates.
Current use: This is the global standard unit used in physics, electrical engineering, and for specifying the strength of electromagnetic coils.
Ampere-turn/meter (At/m)
Definition: Ampere-turn per meter is equivalent to ampere per meter. It specifically refers to the number of turns in a coil multiplied by the current, divided by the length.
History/origin: Developed by electrical engineers to make the design of solenoids and electromagnets more intuitive.
Current use: Commonly found in textbooks and engineering manuals when discussing the magnetic properties of transformers and wound inductors.

How to Convert Ampere/meter (A/m) to Ampere-turn/meter (At/m)
1 am = 1 at_m
1 at_m = 1 am
Example: convert 15 am to at_m:
15 am = 15 × 1 at_m = 15 at_m
Did You Know?
- Did you know? Ampere per meter (A/m) measures the actual magnetic force produced by an electric current flowing through a wire or coil.
- Ampere-turn per meter (At/m) is technically the same as A/m, but engineers use the term "turns" to emphasize how many times a wire is coiled around a magnet core.
