What is the relationship between magnetic field H and flux density B?

Magnetic field strength (H in A/m) is the magnetizing force created by current in a coil. Magnetic flux density (B in Tesla) is the resulting magnetic induction through the medium: B = μ × H = μ₀ × μᵣ × H, where μ₀ is vacuum permeability (4π × 10⁻⁷ H/m) and μᵣ is the relative permeability of the core material.

Why do transformer cores use grain-oriented silicon steel?

Air has a relative permeability μᵣ = 1, meaning weak magnetic fields are produced per ampere-turn. Grain-oriented silicon steel has μᵣ ≈ 4,000–8,000, amplifying magnetic flux density by thousands of times, enabling compact transformer cores without saturation.

How to Convert Newton/square ampere to Henry/meter

Converting Newton/square ampere (N/A²) to Henry/meter (H/m) is a core calculation in Magnetic Permeability, which measures the degree of magnetic induction and magnetization that a material or vacuum obtains in response to an applied magnetic field. Both units share an identical 1:1 scale equivalence within this physical measurement domain. They represent the exact same physical magnitude under different metrological designations or derived SI formulations (1 N/A² ≡ 1 H/m). Any quantity expressed in Newton/square ampere translates directly to Henry/meter without mathematical scaling.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (henry per meter (H/m)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 N/A² = 1 henry per meter (H/m)

2. Target SI Bridge (k_target):1 H/m = 1 henry per meter (H/m)

Step-by-step substitution for Newton/square ampere → Henry/meter:V(H/m) = V(N/A²) × ( 1 / 1 ) = V(N/A²) × 1

Mathematical FormulaValue in Henry/meter = Value in Newton/square ampere × 1Direct computational formula applied for standard conversion.

Worked Example

Converting 36 N/A² yields an exact output of 36 H/m in Henry/meter. Under higher industrial throughput, 100 N/A² translates to 100 H/m.

Inverse check: 1 H/m = 1 N/A².
