### Magnetic field, field strength, and flux density

Magnetic field, field strength, and flux density. In physics, there are two different attributes of a magnetic field: The "magnetic field strength". Usually given the symbol H. Measured in amps per metre (A/m). The "magnetic flux density". Usually given the symbol B. Measured in teslas (or microteslas or gauss). In electromagnetism theory, it is absolutely clear that these are different ...

### Permeability Flux Density Field Strength Magnetism

Permeability is the ratio of the flux density of the magnetic field within the material, to its field strength. u =B/H . u = the permeability of the material measured in Henries per metre (Hm-1). B = flux density measured in Tesla (T). H = the field strength measured in Amperes per metre (Am-1). Relative permeability . When we refer to the permeability of a material, then rather than actually ...

### Magnetic field intensity (H) flux density (B) THE JARGON

12/05/2017  Magnetic field strength is one of two ways that the intensity of a magnetic field can be expressed. Technically, a distinction is made between magnetic field strength H, measured in amperes per meter (A/m), and magnetic flux density B, measured in Newton-meters per ampere (Nm/A), also called Tesla (T). Magnetic flux density (B) is the quantity of magnetic flux (Φ)

### Magnetism: quantities, units and relationships

Flux density is related to field strength via the permeability. B = μ × H. Equation TMD. So for the example core - B = 3.13×10-3 × 18.1 = 0.0567 teslas Equation TMD suggests that the 'B field' is simply an effect of which the 'H field' is the cause. Can we visualize any qualitative distinction between them? Certainly from the point of view of practical coil design there is rarely a need to ...

### Unit Conversion Table of Magnetic Flux Density

Usually, magnetic field strength is defined by the unit of Oe･A/m ( Oersted・Ampere/meter ). And when it is defined by flux density, the units of G (Gauss) or T (Tesla) are used. This means that flux density B is a value which includes magnetizability and magnetic flux H does not include magnetizability.

When the coil current increases so does the magnetic field strength, H. That, in turn, leads to an increase in magnetic flux, . ... One point to note, though, is that flux density is limited by saturation to below about 1.6 teslas. Maxwell's force formula therefore sets a limit on the force of one million newtons per square metre (about 100 tons). [↑ Top of page] The force on materials with ...
