Mumbai University Chemical Engineering Branch Second Year Semister - III Guidance .

Mumbai University Second Year Chemical Engineering Semister - III Guidelines :- Dear Friends if you are unaware of Semister-III of Chemical Engineering and have no idea about it,Then this post can help you out. After your First Year is completed, many of you must be having KT's in one or more subjects or if by chance Passed then you must be having Less Marks between 50-55% or even Less than it ,However some are exceptions who are All Clear with Good Marks. This happens as you all are new to the Semister Pattern of Mumbai University. But...

Elements from the Periodic Table which do not exhibit Magnetism.

NO MAGNETISM a) For a material to be magnetic, it must have electron spin. b) Electron spin gives the substance an Electronic Angular Momentum to interact with the magnetic field. c) Thus if the electrons in an atom spins in the same direction,the atom will produce a magnetic field and will respond to the forces of a magnet. d) But in most atoms,electrons occur in pairs and these paired electrons spin in opposite directions. e) These opposite spins of electrons causes their magnetic fields to cancel each other, such that...

What is Ferromagnetism ? Behaviour of Ferromagnetic Substances & the Elements which exhibit Ferromagnetism..!

FERROMAGNETISM a) The term Ferromagnetism was coined by Curie Pierre in 1895 . b) Those substances which when placed in a magnetic field, are strongly magnetised in the direction of the applied field are called as Ferromagnetic substances. c) A Ferromagnetic substance when placed in a non-uniform magnetic field, show a very strong tendency to move from the weaker to the stronger parts of the magnetic field. d) Ferromagnetic materials are made up of atoms with permanent dipole moments. e) Ferromagnetic substances retain their...

What is Paramagnetism ? Behaviour of Paramagnetic Substances & the Elements which exhibit Paramagnetism..!

PARAMAGNETISM a) The term Paramagnetism was coined by Curie Pierre in 1895. b) Those substances which when placed in a magnetic field are weakly magnetized in the direction of the applied field are called as Paramagnetic Substances . c) A Paramagnetic Substance when placed in a non-uniform magnetic field, begins to move form the weaker region to the stronger region of the magnetic field. d) Thus the magnetic field lines prefer to pass through the Paramagnetic substances and this is the reason why the Paramagnetic Substances...

What is Diamagnetism ? Behaviour of Diamagnetic Substances & the Elements which exhibit Diamagnetism..!

Diamagnetism a) The term Diamagnetism was coined by Michael Faraday in 1845 . b) Those substances which when placed in a magnetic field, are weekly magnetised in a direction opposite to that of the magnetising field are called as Diamagnetic Substances . c) When a Diamagnetic substance is placed in a non-uniform magnetic field , it's atoms acquire a small magnetic dipole moment in a direction opposite to that...
