It is important to note that this equation is only valid when the material is in a paramagnetic state. Presence of magnetic field: The atom gets magnetised due to induced dipole moment . Iron, Nickel, and Cobalt are the magnetic substances as objects made up of these materials are attracted by a magnet. of EECS Instead, they are related by the boundary condition: … Paramagnetic materials are attracted to magnetic fields, hence have a relative magnetic permeability greater than one (or, equivalently, a positive magnetic susceptibility).. Lodestone is a naturally occurring magnet. Magnetic Induction (B) G T 10-4 Applied Field … Magnetic fields can be produced by moving electric charges and the intrinsic magnetic moments … The electron configuration can cause magnetic moments to cancel each other out (making the material less magnetic) or align (making it more magnetic). Paramagnetic materials. The susceptibility of some diamagnetic material (At room temperature)- Note that induced dipole moments occur in all materials and also a dipole moment induced by a magnetic field in a particular atomic model, is independent of the magnetic dipole moment present in the absence of the field.
