The elements lie in d-block or f-block of periodic table and they have large number of unpaired electron which contribute to spin dipole moment so they have large dipole moment and are strongly magnetized. Example:- Fe, Co, Ni, Gd, Dy Since ferromagnetic material is a strongly magnetized the magnetic field line converge when they passed […]


Conducting Material Electrical Carbon Properties This material is made from graphite and other form of carbon. Conductivity of Carbon is less than Copper (Cu) and Aluminum (Al) but its surface is smoother so it is used to make brushes in a Electrical Machine. Carbon brushes are graphited or heat treated to increase conductivity and reduce […]
