-N52-
-“N” MEANS “NEODYMIUM”-
-“52” IS THE “MAXIMUM ENERGY PRODUCT”-
-MEASURED IN “MEGA GAUSS OERSTEDS”-
-IN “SI TERMS”. IT WOULD BE MEASURED AS “KILO-JOULES” PER “CUBIC METER”-
-IT MEASURES “MAGNETIC DENSITY”-
.
“BH CURVE”
-“H” IS “HORIZONTAL AXIS”-
-MEASURES “MAGNETIC FIELD STRENGTH”-
“AMPERES PER METER”
-“B” IS “VERTICAL AXIS”-
-MEASURES “MAGNETIC FLUX DENSITY”-
“TESLAS”
.
.
-THE “B / H” WERE JUST THE LETTERS THAT MAXWELL ASSIGNED TO THE VARIABLES-
.
-“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)
