US4906382A - Method of magnetizing nonmagnetic …

Particles of a nonmagnetic material are rendered magnetic by contacting their surfaces with a magnetizing reagent comprising water containing particles of a magnetic material, each of which has a two layer surfactant coating including an inner layer and an outer layer. The inner layer covers the magnetic particle and is a monomolecular layer of a first water soluble, organic, heteropolar

Learn What Metals Are Magnetic and Why - ThoughtCo

2019-10-2 · Permanent magnets (also known as hard magnets) are those that constantly producing a magnetic field. This magnetic field is caused by ferromagnetism and is the strongest form of magnetism. Temporary magnets (also known as soft magnets) are magnetic only while in the presence of a magnetic field.; Electromagnets require an electric current to run through their coil wires in order to produce a

Magnetism in Stainless Steel Fasteners | Fastenal

Low alloy content stainless steel (particularly that of low nickel, carbon, and/or nitrogen) are more susceptible to MSIT then stainless steel with higher alloying elements. Type 304 is an example of a stainless steel that is quite susceptible to forming martensite after cold working but in fact MSIT affects all austenitic stainless steel to some degree or another.

Why Steel Is Used to Make Permanent Magnets - …

Going back to the basics of this metal, steel is an alloy consisting of iron and carbon. In its natural state, steel isn’t magnetic, but it can be modified in a way that turns it magnetic. When a nonmagnetic piece of steel is applied to a magnet, the atoms within it rearrange themselves in a manner that creates a permanent magnet.
