Much more interesting (also from a technological point of view) are those materials, which not only have a large magnetization, but also retainit even after the removal ofthe external field. We can also say that the diamagnetic substances get repelled by a magnet. DIAMAGNETISM PARAMAGNETISM FERROMAGNETISM PDF. 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. trailer 4@� � P�= Atoms with all diamagnetic electrons are called diamagnetic atoms.

We see that the field lined get repelled by the material and the field inside the material is reduced. 5. Magnetic Dipoles and Magnetic Moments. 0 Comment . Diamagnetism, to a greater or lesser degree, is a property of all materials and will always make a weak contribution to the material’s response to a magnetic field. Diamagnetism is a property of all materials, and always makes a weak contribution to the material's response to a magnetic field. Magnetic Dipoles and Magnetic Moments.
