![]() ![]() Even a ferromagnetic material like iron can exhibit paramagnetic properties after it is heated above a temperature known as the Curie temperature. ![]() The heat energizes atoms and drives them haywire, thereby sending them into disarray. In simpler terms, subjecting a material to heat can alter, or more precisely, impair its magnetic properties. ![]() Lastly, because magnetism is merely a function of atomic arrangement, it can also be achieved through structural deformation by thermodynamic means. The presence of nickel alone can transform magnetic stainless steel to non-magnetic stainless steel. The magnetic properties of stainless steel rely on elements added to the alloy, but the addition of nickel is known to accelerate this transition. These include kitchen basins and fMRI parts, which comprise iron mixed not only with chromium, but also carbon, nickel and manganese to prevent corrosion in the former and deter error-inducing magnetic attractions in the latter. On the other hand, austenitic stainless steel is associated with stainless steel. ![]() Yet, if this has stimulated your curiosity, you can find out more here. The operation of domains itself is quantum mechanical it is, however, irrelevant right now. This is the case with paramagnetic or diamagnetic materials, where the alignment of domains in the former is ordered just enough to be magnetized (aluminum), whereas the order is so haphazard in the latter that it is callous to an approaching magnet (silicon). If the fish were in disarray, the dense arrow they form wouldn’t be comprehensible. The alignment of domains is analogous to the troupe of fish that Nemo’s dad and Dory consult for directions. The material then retains its magnetic properties despite being separated from the magnet! What’s more, the imperfections in iron’s structure are fortuitous, as they prohibit the domains from rotating to their original orientation, even after the field is removed. Iron’s crystalline structure comprises an arrangement where a majority of its domains align in the direction of the magnetic field to which it is subjected. Magnetic attraction is driven by microscopic magnetic units called ‘domains’.Ī domain can be thought of as a miniature compass whose needle points in the direction of a magnetic field. When attracted to an extremely powerful magnet, the iron can often become inseparable. The attraction between a block of iron and a magnet is intense. Iron, the original metal we begin with, is a ferromagnetic material: it shares a highly genial relationship with magnets. ![]()
