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 no net magnetic field is produced and this could be the reason why some elements do not exhibit magnetism.

f) However at a low temperature a substance may have one kind of magnetic properties whereas at a higher temperature it may have another type of magnetic behavior.

g) Thus the conclusion is that Magnetic Properties of a substance is a very complicated topic, and it is very difficult to assign some materials as being strictly magnetic and others to be strictly non-magnetic.
