*’magnetism’ is a ‘class’ of ‘physical phenomena’ that are mediated by ‘magnetic fields’*
.
(“electric currents” + the ‘magnetic moments’ of ‘elementary particles’ give rise to a ‘magnetic field’, which acts on other ‘currents’ and ‘magnetic moments’)
(every material is influenced to some extent by a ‘magnetic field’)
(the most familiar effect is on ‘permanent magnets’, which have persistent ‘magnetic moments’ caused by ‘ferromagnetism’)
(most ‘materials’ do not have ‘permanent moments’)
(some are ‘attracted’ to a ‘magnetic field’ (aka ‘paramagnetism’); others are ‘repulsed’ by a ‘magnetic field’ (aka ‘diamagnetism’); others have a more complex relationship with an ‘applied magnetic field’ (‘spin glass behavior’ / ‘antiferromagnetism’))
(‘substances’ that are negligibly affected by ‘magnetic fields’ are known as non-magnetic substances)
(these include ‘copper’, ‘aluminium’, ‘gases’, and ‘plastic’)
(‘pure oxygen’ exhibits ‘magnetic properties’ when cooled to a ‘liquid state’)
(the ‘magnetic state’ (or ‘magnetic phase’) of a material depends on ‘temperature’ and other ‘variables’ such as ‘pressure’ and the ‘applied magnetic field’)
.
.
(a ‘material’ may exhibit more than 1 form of ‘magnetism’ as these ‘variables’ change)
