DIFFERENCES FERRI & FERRO (HAZIQAH 4 SSCZ)
ferrimagnetism
:checkered_flag: occurs in an oxide of iron
:check: magnetite
:checkered_flag: neighboring magnetic domains lie in opposite directions
:checkered_flag: small differences between neighboring domains makes a magnetic field possible
:checkered_flag: making the first navigational compass
:checkered_flag: magnetism is a result of the alignment of tiny regions
ferromagnetism
:black_flag: elements such as iron, nickel and
cobalt
:black_flag: the magnetic domains align in the same direction
:black_flag: parallel to each other to produce strong permanent magnets
Curie Temperature
:red_flag: Objects become magnetized when a large number of microscopic magnetic domains align
:red_flag: high temperatures, however, the atoms in the object vibrate
:red_flag: Ferro have higher Curie Temperatures than ferri
Alignment of magnetic dipole
:<3: ferri
:check: point in the same
direction and some in the opposite direction
:<3: ferro
:check: they all point in the same direction
:check: a stronger magnetic field
