In contrast, the opposite behavior is exhibited by paramagnetic materials. Diamagnetism is a quantum mechanical effect that occurs in all materials; when it is the only contribution to the magnetism the material is called a diamagnet.Unlike a ferromagnet, a diamagnet is not a permanent magnet.Its magnetic permeability is less than Î¼ 0, the permeability of vacuum. In most materials diamagnetism is a weak effect, but a superconductor repels the magnetic field entirely, apart from a thin layer at the surface.nlike a ferromagnet, a diamagnet is not a permanent magnet.

The use of asbestos in new construction projects has been banned for health and safety reasons in many developed countries or regions, including the European Union, Australia, Hong Kong, Japan, and New Zealand.
1 Asbestosis is a process of lung tissue scarring caused by asbestos fibers. 2  Asbestos is the only known risk factor for malignant mesothelioma, a cancer that affects the tissue lining the lung (pleura) or abdomen (peritoneum). Diagnosis of asbestosis or asbestos-related lung diseases and cancer is often made using chest X-rays or CT scans of the lungs. 2  Treatment of asbestos-related diseases includes appropriate vaccinations, treatment of lung infections, smoking cessation, and the use of oxygen if necessary.
