Magnetic Materials

Cobalt magnets, notable for their remarkable magnetic properties, have become vital in numerous high-tech applications, ranging from electric vehicles to wind turbines. Cobalt, a transition metal with the atomic number 27, contributes significantly to the alloy’s ability to withstand high temperatures and exhibit magnetic solid performance. Cobalt-based magnets offer superior coercivity and energy when alloyed […]

In the quest to comprehend the magnetic properties of tin, it is pivotal to understand the principles governing magnetism in materials. Tin (Sn), a post-transition metal, is primarily diamagnetic. This implies that, when exposed to an external magnetic field, tin induces a weak, negative magnetic moment that opposes the direction of the applied field. The

A magnetic field is an invisible force that exerts a magnetic influence on moving electric charges, guiding their path and direction. It originates from electric currents, macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits. The strength of a magnetic field is measured in Tesla (T) in the International System of

Nickel is indeed magnetic, though its magnetic properties are less pronounced than those of iron, cobalt, and gadolinium, considered the only purely ferromagnetic elements at room temperature. The phenomenon behind nickel’s magnetism is its electron configuration, allowing it to generate a magnetic field. Interestingly, nickel’s magnetic properties depend highly on its temperature, with its ferromagnetism

Brass is commonly perceived as a non-magnetic material. This characteristic can primarily be attributed to its composition—brass is an alloy consisting predominantly of copper (Cu) and zinc (Zn), both of which are metals not known for their magnetic properties. The percentage of copper can vary between 55% and 95% depending on the type of brass,

Iron is indeed magnetic, a property that categorizes it as a ferromagnetic material. This characteristic can be primarily attributed to the alignment of its electron spin. In ferromagnetic materials like iron, electrons in atoms spin synchronized, generating an intense magnetic moment. Consequently, when exposed to an external magnetic field, these moments tend to align themselves

Copper, a ductile metal with excellent thermal and electrical conductivity, exhibits a fascinating relationship with magnetic fields that counters the typical behavior observed in ferromagnetic materials like iron, cobalt, and nickel. Contrary to these materials, copper is not inherently magnetic in the traditional sense. It does not retain magnetization in an external magnetic field, a

Silver, in its purest form, is not magnetic. This distinct characteristic stems from the metal’s electronic structure and lack of unpaired electrons, which are necessary for a material to exhibit ferromagnetism. The magnet test, therefore, serves as a simple, albeit not wholly definitive, method to determine if an item that claims to be silver is
