Non-ferromagnetic materials tend to have paired electrons in each orbital or very less unpaired electrons.

Example - Neon, its atomic number is 10 and all the electrons are pared. Now, Aluminum. Its atomic number is 13 with the electronic configuration 3[tex] p^{1} [/tex] i.e. only one unpaired electron in the p- orbital. Now, consider iron its atomic number is 26 and its configuration is 3[tex] d^{6} [/tex]. It has more number of unpaired electrons.  Thus, neon is non-magnetic, aluminum is also non-magnetic but iron is magnetic.

Answer:

Non-ferromagnetic materials tend to have paired electrons in each orbital.

Explanation:

The non ferromagnetic materials have all paired electrons in each orbital, or a small number of unpaired electrons.

This can be justified given that the pairing of electrons with opisite spins (one with -1/2 and the other with +1/2)  counteracts the magnetic properties that the element could have.
