One of the drawbacks in using steel in the early years was, as the material became older, the losses would increase. Magnetic susceptibility, k, is related to magnetic permeability (m) by: An example of image distortion is shown in Figure 16.16. A synonym for susceptibility is "magnetizability". The proportional constant links magnetization to the applied magnetic field intensity (at levels below which saturation and hysteresis are important). (1982). Stainless Steel. O'Connor, C.J. However, this does not mean that you should expect to measure such a low susceptibility on any item of 304 or 316 stainless steel that you encounter. Paramagnetic, ferromagnetic, antiferromagnetic, and ferrimagnetic solids all have χ > 0, but the magnitude of their susceptibility varies with the kind of ordering and with temperature. An alloy steel becomes a stainless steel if … This grade of steel contains 98.81 to 99.26% iron. Magnetization and susceptibility . In this case, a simple relationship is obtained in terms of 𝐻 • The difference in mass of the sample with and without the magnetic field corresponds to magnetic susceptibility of the sample. Some stainless steels are magnetic and some are not. In a previous blog posting about magnetic permeability, we discussed why ferrous materials are attracted to a magnet: the magnet’s magnetic field induces a magnetic field into the steel and the fields interact, such that, the magnet and the steel attract. Note: This article is taken from Atlas Specialty Metal Tech Note 11 "Magnetic Response of Stainless Steel" Magnetic response – or the lack of it – is often one of the first things that people think of as a basic property of stainless steels. Magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field. • F= χ m mH(dH/dz) where χ m is magnetic susceptibility per unit mass and m is mass of the sample. Thus, a very high percentage of this steel grade is iron. Susceptibility is a measure of the extent to which a substance becomes magnetized when it is placed in an external magnetic field. Introduction to Silicon Steel Silicon steel was one of the first alloys to be used in transformers and inductors. It has been greatly improved over the years and is probably, pound for pound, the most, widely used magnetic material. Magnetic susceptibility is a dimensionless proportionality factor that indicates the degree of magnetization of a material in response to an applied magnetic field. The magnetic susceptibility, χ, of a solid depends on the ordering of spins. It is caused by interactions of electrons and nuclei with the externally applied magnetic field. • The mass of the sample is taken with and without the magnetic field. This corresponds to a somewhat larger magnetic susceptibility than we might expect for other nonmagnetic materials, but is still well below what might be considered magnetic. 𝑓 is the initial magnetic susceptibility for ferrite, which is related to the [initial permeability via 2] 𝜇𝑖 𝑓=1+4𝜋𝜒 𝑖 𝑓 (7) As for the maximum permeability, it is convenient to relate 𝜇𝑖 𝑓 to other more readily available magnetic properties. When matter interacts with the magnetic field, an internal magnetization or polarization (J) is created that either opposes or augments the external field. Hence, the ferromagnetic properties of iron transfer to steel. Magnetic susceptibility is a measure of the ability of a material to be magnetized. Due to the very low bandwidth in the phase-encoded direction, considerable image distortion can be produced in regions with off-resonance effects, such as field inhomogeneity, magnetic susceptibility variations, eddy currents with long time constants (e.g., > 100 ms), and concomitant magnetic fields.
