  • Why Steel Is Used to Make Permanent Magnets

    Aug 07, 2019 · Steel is highly effective for this purpose because of the natural positioning of its atoms. Steel isn't the only material used to make permanent magnets. Permanent magnets are also made of ceramic, iron, cobalt, nickel, gadolinium and neodymium. With that said, steel is a relatively inexpensive and widely available material, even more so than ...

    The higher the number, the better the shield. Low carbon steels have a Permeability of 1000 3000, while MuMetal can have values as high as 300,000 400,000. The saturation point is the flux density at which the material can not contain any more magnetic flux. Steel saturates around 22,000 Gauss, while MuMetal saturates at about 8,000 Gauss.

  • Why soft magnetic material is used in transformer?

    Answer (1 of 3): Transformer core requires magnetization, demagnetization and reverse magnetization during operation. The energy expended in doing so in the form of hysteresis losses should be minimum. This corresponds to low coercive force on the magnetization curve of the material and small are...

    The magnetic mild steel is used for relays and poles pieces for electromagnets. A typical ferrite, the MnZn ferrite, is listed mainly for one reason. This ferrite, like all the rest of the ferrites, is a good insulator so that p is relatively high. Thus the eddycurrent loss is vanishingly small, even in unlaminated section.

  • What is Martensite

    This allows for varying levels of strength. In metallurgy, quenching is most commonly used to harden steel by introducing martensite. There is a balance between hardness and toughness in any steel; the harder the steel, the less tough or impactresistant it is, and the more impactresistant it is, the less hard it is.

  • Soft Magnetic Materials

    The main parameter, often used as a figure of merit for soft magnetic materials, is the relative permeability (m r, where m r = B/m o H), which is a measure of how readily the material responds to the applied magnetic field. The other main parameters of interest are the coercivity, the saturation magnetisation and the electrical conductivity.
