diamagnetism and paramagnetism?

Question

define them in a simple words/phrase....

Answer 1

paramagnetism is the magnetic property exhibited by substances in which each atom or molecule has a net non zero magnetic moment of its own

diamagnetism is the magnetic property exhibited by substances in which net magnetic moment of atom is zero

Answer 2

Diamagnetic resources have a weak, adverse susceptibility to magnetic fields. Diamagnetic resources are somewhat repelled by technique of a magnetic container and the fabrics does no longer preserve the magnetic residences at the same time as the exterior container is got rid of. In diamagnetic resources each and every of the electron are paired so there is not any everlasting internet magnetic second consistent with atom. Diamagnetic residences upward push up from the realignment of the electron paths less than the impact of an exterior magnetic container. maximum aspects contained in the periodic table, which includes copper, silver, and gold, are diamagnetic. Paramagnetic resources have a small, effective susceptibility to magnetic fields. those resources are somewhat attracted by technique of a magnetic container and the fabrics does no longer preserve the magnetic residences at the same time as the exterior container is got rid of. Paramagnetic residences are via presence of a few unpaired electrons, and from the realignment of the electron paths brought about by technique of the exterior magnetic container. Paramagnetic resources contain magnesium, molybdenum, lithium, and tantalum. Ferromagnetic resources have a huge, effective susceptibility to an exterior magnetic container. They show a strong attraction to magnetic fields and are able to preserve their magnetic residences after the exterior container has been got rid of. Ferromagnetic resources have some unpaired electrons so their atoms have a internet magnetic second. They get their strong magnetic residences via presence of magnetic area names. In those area names, tremendous numbers of atom's moments (1012 to 1015) are aligned parallel so as that the magnetic stress in the area is powerful. at the same time as a ferromagnetic fabric is contained in the unmagnitized state, the area names are almost randomly prepared and the internet magnetic container for the area as an finished is 0. at the same time as a magnetizing stress is utilized, the area names develop into aligned to provide a strong magnetic container in the area. Iron, nickel, and cobalt are examples of ferromagnetic resources. aspects with those resources are in many cases inspected utilizing the magnetic particle approach.
