Magnetic field strength is a key parameter in understanding magnets. As a manufacturer, we often need to measure it accurately. This article explains how to measure magnetic field strength and its importance.
Magnetic field strength is measured using a gauss meter[1] or a tesla meter[2]. The unit for magnetic field strength is tesla (T) or gauss (G). The formula is B = μ₀(H + M), where B is the magnetic flux density, H is the magnetic field strength, and M is the magnetization. Accurate measurement is crucial for various applications, from industrial to medical.
What is Magnetic Field Strength?
Magnetic field strength is a measure of the intensity of a magnetic field. It is crucial in many industries.
Magnetic field strength (H) is the force exerted by a magnet on a unit magnetic pole. The formula is H = B/μ₀ – M, where B is the magnetic flux density[3], μ₀ is the permeability[4] of free space, and M is the magnetization. This formula helps in understanding the relationship between different magnetic properties.

Understanding the Formula
The formula for magnetic field strength is essential for accurate measurements. Let’s break it down:
Symbol | Meaning |
---|---|
B | Magnetic Flux Density |
μ₀ | Permeability of Free Space |
M | Magnetization |
As a manufacturer, we use this formula to ensure our products meet industry standards. Accurate measurement is crucial for applications like MagSafe magnets and neodymium magnets.
Is Magnetic Field Strength H or B?
Understanding the difference between H and B is essential for accurate measurements.
Magnetic field strength is represented by H, while B represents magnetic flux density. H is the external magnetic field, and B is the total magnetic field, including the material’s magnetization. The relationship between them is given by B = μ₀(H + M).

Practical Applications
Understanding these terms is crucial for manufacturers. For example, we need to measure H and B accurately for our neodymium magnets[5] and MagSafe products[6].
