Commercial magnetically soft materials are usually made from alloys of iron and nickel with compositions around Ni80Fe20. Commercial materials have names like 'Permalloy', 'Hymu' and 'Mumetal' and are characterized by high initial permeability and narrow, square hysteresis loops.

Översättning av ordet magnet från engelska till norska med synonymer, motsatsord core a bar of magnetic material (as soft iron) that passes through a coil and

Some materials like iron are magnetically soft. They lose their magnetism once they are no longer exposed to a magnetic field. They are used as temporary magnets such as electromagnets. Steel was a formerly used material to produce permanent magnets and the terminology "magnetically hard" is based on the hardened steel in contrast to the "magnetically soft" properties of soft iron. Today Samarium-Cobalt or Neodymium-Iron-Boron alloys are used to form permanent magnets. 2020-10-07 · In this contribution a magnetoactive elastomer (MAE) of mixed content, i.e., a polymer matrix filled with a mixture of magnetically soft and magnetically hard spherical particles, is considered.

Magnetically hard materials (e.g. Steel): Are hard to magnetise; Do not easily lose their magnetism; Permanent magnets are made out of magnetically hard materials, as we don’t want them to lose their magnetism; Electromagnets are made out of magnetically soft materials, as we want them to be able to easily gain and lose their magnetism

Pure […] Magnetically soft materials Materials with low coercive field strengths are referred to as magnetically soft material. Materials that are especially magnetically soft include, among others, the material Supermalloy, which is used, for example, to shield rooms in which brain waves are measured.

To increase the efficiency of magnetic thermal induction by NPs, one can take magnetically hard material (CoFe2O4) has been coupled to a soft material

Difference Between Soft and Hard Magnetic Materials are as Follows: 2002-05-02 While those substances that can be temporarily magnetized are termed as magnetically soft materials. Alloys with a low percentage of iron, cobalt and nickel fall under this category. So when soft material is placed in the magnetic field it gets temporarily magnetized because domains will easily realign themselves and again get randomized after the removal of the magnetic field. An analogous property in electrical engineering and materials science, electric coercivity, is the ability of a ferroelectric material to withstand an external electric field without becoming depolarized.. Ferromagnetic materials with high coercivity are called magnetically hard, and are used to make permanent magnets.Materials with low coercivity are said to be magnetically soft.

A magnetically hard substance is one which can be permanently magnetised using a strong magnetic force.

Soft-magnetic materials are subdivided into two groups according to their function: materials for weak-current equipment and for electrical steel. Binary and other Fe-Ni alloys (Permalloys), which have low H c (≈ 0.01 oersted) and very high μ a (up to 10 5 ) and μ max (up to 10 6 ), are the most important representatives of the soft-magnetic materials used in weak-current technology.
