magnetized SusceptabilityAbstractThe change in weight induce by a magnetic sketch for three solutions ofcomplexes was recorded. The change in weight of a calibrating solution of 29.97%(W/W) of NiCl2 was recorded to bet the apparatus constant as 5.7538. cvand cm for each solution was determined in order to calculate the number of mismatched electrons for each paramagnetic complex. Fe(NH4)2(SO4)26(H20) had 4unpaired electrons, KMnO4 had cypher unpaired electrons, and K3Fe(CN)6 had 1unpaired electron. The apparent 1 unpaired electron in K3Fe(CN)6 when thereshould be five according to atomic orbital calculations arises from a strongligand field produced by CN-.IntroductionThe magnetic talent is a phenomena that arises when a magnetic jiffy is induced in an prey. This magnetic arcsecond is induced by the presenceof an external magnetic field. This induced magnetic secondment translates to achange in the weight of the object when placed in the presence of an externalmagnetic fie ld. This induced moment may have dickens orientations parallel to theexternal magnetic field of or perpendicular to the external magnetic field. Theformer is known as paramagnetism and the later is known as diamagnetism. The fleshly effect of paramagnetism is an attraction to the semen of magnetism(increase in weight when measured by a Guoy balance) and the physical effect ofdiamagnetism is a repulsion from the source of magnetic field (decrease inweight when measured by a Guoy balance).The observed magnetic moment is derived by the change in weight. Thisobserved magnetic moment arises from a combination of the orbital and spinmoments of the electrons in the sample with the spin subdivision being the mostimportant source of the magnetic moment. This magnetic moment is caused by thespinning of an electron around an axis acting desire a tiny magnet. This spinningof the magnet results in the magnetic moment.Paramagnetism results from the long-lasting magnetic moment of the atom.Th ese permanent magnetic moments arise from the presence of unpaired electrons.These unpaired electrons result in unequal number of electrons in the twopossible spin severalises (+1/2. -1/2). When in the absence of an external magneticfield, these spins tend to orient themselves randomly accordingly to statistics.When they are placed in the presence of an external magnetic field, the momentstend to align in directions anti parallel and parallel to the magnetic field.According to statistics, more electrons will pertain the lower energy state thenthe higher energy state. In the presence of a magnetic field, the lower energystate is the state when the magnetic moments are aligned parallel to the
