Why aluminium is not attracted by a magnet?

Answer 1

magnetism arises from the spin of electrons in their orbitals. most electrons in atoms are paired so that their magnetic fields cancel but certain atomic structure contain unpaired electrons.

these are what gives atoms magnetism. metallic aluminum has the electron configuration of 1s2 2s2 2p6 3s2 3p1 there is one unpaired electron in the 3p orbital is considered to be paramagnetic. although this is largely quenched by the strong delocalization in the p and s orbital. those magnetic substances that are paramagnetic, the orientation of the electron spins are random and has no net field in a macroscopic scale(permanent magnet behaviour). they are only observable by their interaction with anther strong magnetic field that causes the many small fields to align and a small net attraction

this is quantitatively measured by a gouy balance to give a measurement called the magnetic suscepitability which can be corrolated to the number of unpaired electrons (this is espcially useful for the analysis of transition metal compounds)

Answer 2

Aluminum is not attracted to a magnet because it is classified as a paramagnetic metal. The atoms in the metal must all be spinning in the same direction for magnets to attract. With aluminum, they are spinning in different directions.

Answer 3

because its not dense metal only dense metals like iron are magnatic as the spaces belween atom increase the magnetism will vanish

Answer 4

Because it does not contain copper, iron, there is one more but i cant remember it, hope this helps

Answer 5

the mangetic structure e.g. flows in one direction unlike two directions; i don't know sorry but this is what i know

Answer 6

Because the lack of carbon.

Answer 7

it has no magnets in it

Answer 8

cause it isn't
