Relation between electricity and magnetism?

[akashpandey]

Why flowing current in wire creat magnetic field...if anybody say this is because of spin quantum number,...
So i just want to say spin quantum number is because of wave nature of electron.i just want to know what effect of dual nature of electron on magnetic field.

This is what I used to get my head around what's happening.

Its got nothing to do with QM - its a relativistic effect:

The deep reason for both electricity and magnetism however is quantum:

This dual nature wave particle stuff is a myth:
