Diamagnetic, Paramagnetic and Ferromagnetic MaterialsMaterial
Diamagnetic, Paramagnetic and Ferromagnetic Materials
Material on the basis of Magnetism are classified as Diamagnetic, Paramagnetic and Ferromagnetic
Diamagnetic materials have weak, negative susceptibility to magnetic fields.
These materials are slightly repelled by a magnetic field and the material does not retain the magnetic properties when the external field is removed
Diamagnetic
In diamagnetic materials all the electrons are paired so there is no permanent net magnetic movement per atom
Diamagnetic Properties arise from realignment of the electron paths under the influence of an external magnetic field
Most element like copper, silver and gold are diamagnetic
Paramagnetic
Paramagnetic materials are most like diamagnetic but they are slightly attracted by a magnetic field and does not retain the magnetic properties when the external field is removed.
Paramagnetic magnetic properties are due to the presence of some unpaired electrons and from the realignment of the electron's paths caused by external magnetic field.
Paramagnetic materials include magnesium, molybdenum, lithium, and tantalum
Ferromagnetic materials
Ferromagnetic materials have a large, positive susceptibility to an external magnetic field. They exhibit a strong attraction to magnetic fields and are able to retain their magnetic properties after the external field has been removed.
Ferromagnetic materials have some unpaired electrons so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains. In these domains, large numbers of atom’s moments (10^12 to 10^15 are aligned parallel so that the magnetic force with in the domain is strong. When a ferromagnetic material is in unmagnitized state, the domains are nearly randomly organized and the net magnetic field for the part as a whole is zero. When a magnetizing force is applied, the domains become aligned to produce a strong magnetic field within the part.
Iron, nickel, and cobalt are examples of ferromagnetic materials.
