The concept of magnetic field intensity also turns out to be useful in a certain problems in which (mu) is not a constant, but rather is a function of magnetic field strength. In this case, the magnetic behavior of the material is said to be nonlinear. For more on this, see Section 7.16.
Magnetic data (Cordell and Taylor 1971) were obtained by means of a Varian proton-precession magnetometer and figure 8(a) shows the residual magnetic field (TMI) of the Gillis seamount obtained by removing the International Geomagnetic Reference Field (IGRF) (Fabiano and Peddie 1969) from the total intensity data and adjusting the …

Fig. 2 a shows that a permanent magnet with a 30-mm gap was affixed to the cutting tool. the magnetic intensity, ranging from 0.01 T to 0.25 T, was varied by using permanent magnets with different intensities. Specifically, the magnetic field intensity refers to the intensity at the tool nose, which is measured by a Gaussmeter (DEXIN MAG, DX-1205 F).
We can continuously change the area of the loop (A) , or the strength of the magnetic field (B). But it's usually more convenient and practical to continuously change the angle between the surface-normal and the field (θ). This can be accomplished by rotating the loop or the magnetic field. This is how electric generators work.
As is shown in Fig. 8 (a), when the magnetic field gradient is 5 × 10 6 A/m 2 and the magnetic field intensity H is in the range of 60–160 kA/m, the value of F mm /F m increases with increasing relative permeability of the particles and the magnetic field intensity; when the relative permeability of particles is 1.7–4.1, the magnetic ...
Moreover, the sensor responding to the 50-Hz alternating magnetic field is also experimentally investigated, and a minimal detectable magnetic induction intensity of ~23.7 Gs is successfully achieved. The proposed magnetic field sensor is attractive due to its compact size, low cost, and immunity to electromagnetic interference.

Magnetic Field Intensity Unit. Magnetic field intensity is also known as the magnetizing force which is measured is ampere-turns per meter (A-t/m). Of primary concern, however, is the magnetomotive force needed to establish a certain flux density, B in a unit length of the magnetic circuit.

Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic is defined in ASME Section V as "a term applied to materials that can be magnetized or strongly attracted by a magnetic field."
Part Two: Measure Strength One might choose to view magnetic strength through the lens of pull force or magnetic field. The pull force is essentially the force needed to pull two magnets apart, or to remove a magnet from some other surface, like steel. While the magnetic field is the measurement of strength and direction at a specific point.

The force that a unit north – pole experiences when it is put in a magnetic field is described as the magnetic intensity at that location. The magnetic field strength at P owing to a single pole is given by: The magnetic field B, we argue, may be expressed as: B = (μ 0 ⁄ 4 π) (m / π r 2) We know, μ0 ⁄ 4 π = 10 −7
Magnetic fields may be represented by continuous lines of force or magnetic flux that emerge from north-seeking magnetic poles and enter south-seeking magnetic poles. The density of the lines indicates the magnitude of the magnetic field. At the poles of a magnet, for example, where the magnetic field is strong, the field lines are …
