Magnetic field lines paramagnetic material. However if we remove the applied field the materials tend to lose their magnetism. Paramagnetic materials have a permanent dipole moment or permanent magnetic moment. Diamagnetic paramagnetic and ferromagnetic substances. Asked mar 7 in physics by shasiraj 62 4k points cbse.
Two identical bars one of paramagnetic material and other of diamagnetic material are kept in a uniform external magnetic field parallel to it. Paramagnetic properties are due to the presence of some unpaired electrons and from the realignment of the. Paramagnetic materials have a small positive susceptibility to magnetic fields. Paramagnetic materials are materials that tend to get weakly magnetized in the direction of the magnetizing field when placed in a magnetic field.
In contrast paramagnetic and ferromagnetic materials are attracted by a magnetic field. Iii the magnetic susceptability chi m of a paramagnetic material has a small positive value ie. In contrast with this behavior diamagnetic materials are repelled by magnetic fields and form induced magnetic fields in the direction opposite to that of the applied magnetic field. When a bar of paramagnetic material is placed in a magnetic field the lines of force tend to accumulate in it.
Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field and form internal induced magnetic fields in the direction of the applied magnetic field. As the material acquires a net magnetic dipole moment that is it is magnetized in the direction of and the field lines become denser inside the paramagnetic material compared to those outsides. An applied magnetic field creates an induced magnetic field in them in the opposite direction causing a repulsive force. Paramagnetic materials characteristically align with and strengthen an external magnetic field while diamagnetic substances partially expel an applied field and always align themselves so that they are perpendicular to its lines of magnetic force.
Science physics magnetism types of magnetic materials in this article we shall study types of magnetism types of magnetic material and curie temperature. When it is the only contribution to the magnetism the. Properties of paramagnetic materials. Diamagnetism is a quantum mechanical effect that occurs in all materials.
If a bar of paramagnetic material is suspended in between the pole pieces of an electromagnet it sets itself parallel to the lines of force. The atoms of material undergo thermal agitation. Ii when a paramagnetic material is placed inside a magnetic field the magnetic field lines become slightly more dense in the paramagnetic material. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed.
