Your question is useless when compare to my theory, moreover you don’t understand what I am speaking so only you go for that question

Incomplete inner electron sub shell is source or result for magnetisms.
Can you tell me what is the true reason for this incomplete inner electron sub shells??????

Now let us see in true science view, present magnet (matter) are composed of two magnetic particles such as nucleus and electron. So matter consists of two unlike magnetic force of nucleus magnetic force and electron magnetic force. Nucleus magnetic force was the primary force of matter, this primary magnetic force group together at center of gravity of matter. Primary magnetic force keeps undercontrol or neutralizes the secondary electron magnetic force. But in present magnet some secondary electron magnetic force of electron group together and work against or repels primary magnetic force of nucleus because of it unlike magnetic force. This was the true reason for the incomplete inner electron sub shells.

In Simple about: present magnet
Fight in-between two unlike magnetic force of nucleus and electron is present magnet
