Electrical conductivity varies from metals to insulators. Solids can be divided into three categories: conductors, insulators, and semiconductors. Conductors are solids through which electricity can flow to a large extent, classified as...

Ferromagnetic materials, such as Fe and Ni, exhibit permanent magnetism even when the magnetic field is removed. These materials are formed by the spontaneous alignment of magnetic moments due to unpaired electrons in the same...

Materials can be classified based on their response to external magnetic fields. Diamagnetic materials are weakly repelled by external magnetic fields, while paramagnetic materials are attracted but lose their magnetism in the absence...
