magnetic field strength, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre.

It has been common practice to define another magnetic field quantity, usually called the "magnetic field strength" designated by H. It can be defined by the relationship H = B/μ m = B/μ 0 - M
29 kwi 2024 · Magnetic Field Strength Formula. The magnetic field around any electromagnet can easily be calculated using the formula, [Tex]B = \frac {\mu _ {0}I} {2\pi r} [/Tex] where, μ0 is the Permeability of Free Space I is the Magnitude of Electric Current r is the Distance in Meters.
Magnetic field strength is a measure of the intensity of a magnetic field in a given area of that field. Represented as H, magnetic field strength is typically measured in amperes per meter (A/m), as defined by the International System of Units (SI).
The strength of the field of force, the magnetic field strength, or magnetizing force H, may be defined in terms of magnetic poles: one centimeter from a unit pole the field strength is one oersted.
The unit of H, magnetic field strength, is ampere per meter (A/m). [5]: 22 B and H differ in how they take the medium and/or magnetization into account.
Magnetic field strength is measured in amperes per meter (A/m), indicating how much current contributes to the magnetic field in that space. In vacuum or air, the relationship between magnetic field strength (H) and magnetic flux density (B) is defined by the equation $$B = \mu_0 H$$, where $$\mu_0$$ is the permeability of free space.
