According to the text,

neither in diamagnetic materials nor in paramagnetic materials the electrons are paired.

the susceptibility of a magnetic field may be positive or negative, according to its stength.

the alignment of all electron paths when there’s an external magnetic field is typical of elements like magnesium and molybdenum.

most elements in the periodic table are somewhat attracted by an external magnetic field.

the magnetic property retention is absent both in diamagnetic and paramagnetic materials when the external magnetic field is taken away.
