Wie der Diamagnetismus beschreibt er das magnetische Verhalten eines Materials, das einem externen Magnetfeld ausgesetzt ist. 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. Diamagnetic materials have a weak, negative susceptibility to magnetic fields. 0000001421 00000 n 0000000576 00000 n 0 Comment . Whereas the effects of paramagnetism and diamagnetism in a material are small and change κ m only slightly from its value of unity for free space, the effect of ferromagnetism is very large.

It is convenient to group the magnetic properties of solids under the following headings: (i) diamagnetism (ii) paramagnetism (iii) ferromagnetism, antiferromagnetism, ferrimagnetism However, other forms of magnetism (such as ferromagnetism or paramagnetism) are so much stronger that, when multiple different forms of magnetism are present in a material, the diamagnetic contribution is usually negligible. However, for materials that show some other form of magnetism such as ferromagnetism or paramagnetismthe diamagnetic contribution becomes negligible. Asked by: abraham j a Answer In short, the definitions go like this: Diamagnetism refers to materials that are not affected by a magnetic field.Paramagnetism refers to materials like aluminum or platinum which become magnetized in a magnetic field but their magnetism disappears when the field is removed. 0000003397 00000 n 3��1F#�v9X�~��[9z'�ӛͿ���R/+���dw"G�V�ϡ�I��~E�}��;�zX'�?���Y�d���n��)kC���bw�F����_���Ua��v�უ��_�XkbH��Uz��%��v���7Zh:��7 ��F�t_��(��E[��*ꪭp ׃\X�"W��N]Q���=J���7;�3:6B?߹щ4]�/�ҫ�#L��ӿn�|���F�?��7�:�%n�1�Z���z�|s�yI��/����� ��Ƅ��MH�l�����+Xd�l�X.7Z��fw��[�=���Jh�}�*�O[sY+ߤJi���* Ǡ�� Diamagnetism is the property of material which causes it to create a magnetic field in opposition of an externally applied magnetic field, thus causing a repulsive effect.. Paramagnetism is a form of magnetism which occurs only in the presence of an externally applied magnetic field. The main difference between diamagnetism, paramagnetism, and ferromagnetism is that diamagnetism refers to a type of magnetism which forms in opposition to an external magnetic field and disappears … 5. stream DIAMAGNETISM PARAMAGNETISM FERROMAGNETISM PDF. endstream endobj 153 0 obj<> endobj 154 0 obj<> endobj 155 0 obj<>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC/ImageI]/ExtGState<>>> endobj 156 0 obj<> endobj 157 0 obj[/ICCBased 162 0 R] endobj 158 0 obj[/Indexed 157 0 R 15 163 0 R] endobj 159 0 obj<> endobj 160 0 obj<> endobj 161 0 obj<>stream x�b```f``���$�22 � +P����C�@Iis��@��|F��&�]!��Y���E��-S�煎�}[�D�00E�cz{����+OY�[���{}y��c"J�>���e��{�b`�����N���W�Jg4�15���,�S�$ Ա�W-<1�(綹��':d$(��� ��y���m��b�V6�p[�L�DL}j��E��`C����> it��v&x�#��I���±��c"j��L �� �������r)�L�lC�҃�+E�3=h[Ǔ�����ag����P7���K�$t3��qG$l��`�0 The magnetism exhibited by these substances is called paramagnetism.
