What Is Ampere Turn/Meter?

An ampere-turn per meter (AT/m) is another name, now obsolete, of the SI-derived unit of magnetic field strength, which is also called magnetic field intensity or H-field. “ Turn” in ampere-turns refers to the winding number of an electrical conductor comprising a solenoid or inductor.

What is meant by Ampere-turn?

: the meter-kilogram-second unit of magnetomotive force equal to the magnetomotive force around a path that links with one turn of wire carrying an electric current of one ampere.

Is ampere a meter?

The ampere per meter (symbolized A/m) is the International Unit of magnetic field strength. It is derived from basic standard units, but is expressed directly in base units and cannot be further reduced. ... For a given coil, the magnetic field strength is directly proportional to the linear current density.
