Is magnetisation of a para and ferromagnetic substance a deviation from lenz law
Asked by | 09 Oct, 2008, 11:46: AM
Expert Answer
Diamagnetic substances have non-magnetic atoms. The diamagnetic effects are due to the change in the orbital motion of the electrons under the applied magnetic field. According to Lenz's law the induced currents give rise to a flux that is opposite to the changing applied field.
This magnetism also exists in para and ferromagnetic substances. But it is so weak that it is completely masked by the contribution of the magnetic atoms.
