Diamagnetism results from the interaction of paired electrons with an applied magnetic field, therefore all matter is diamagnetic. Attraction and repulsion of Magnetic materials. Paramagnetic. From microscopic point of view, these are the substances whose atomic orbitals are completely filled. So the diamagnetic terms win. [Note, by the way, that paramagnetism can also receive contributions from orbital angular momentum.[. Materials like water, copper, nitrogen, barium sulfate, and most tissues are diamagnetic. A substance is paramagnetic when it has at least one unpaired electron and a substance is diamagnetic when it has no unpaired electron. I have learned that copper is supposed to be diamagnetic. Metals are generally found in the ores of other elements or minerals and exhibit hard and solid metallic luster. It is a paramagnetic diradical. Technically, they are repelled by the poles of a magnet, but this repulsion is usually too small to notice. ��V����r�~�!A��a�0�w�'8��x��&���>����=���CH�*��:b�?�x�k�>��;H"�����z[�:��r› I8�����j����5��?ښCJA]������u�B�Pz�l���p� Ң�ȧ�)��QC�CF���[���F�#A��8�o#d��*Q8#�MU" �gQ�� m$���>��f�_S��a$��Iv���o�R�d��%��k�0�fQl�Ez���j�U�]�M髌����g�:�J��̬�9�����I�p�������ͮ��w8v8l�e!�o��L7x{��5���L���JӉ�R"(�X)� That is why it is diamagnetic.
