Process of making a material magnetic
Maintains magnetic field after being magnetised
Tiny regions where electron fields are aligned
Point in random directions, cancel out
Aligned domains grow, un-aligned shrink
All unpaired electrons aligned with external field
Magnetisation retained after external field removed
Higher temp = more random = lower magnetisation
Material placed in solenoid with large magnetic field
Alternating N-S domains attract and repel
