Questão 12
Questão
In a magnet, there are areas called [blank_start]domains[blank_end], each of which behaves like a tiny [blank_start]magnet[blank_end]. In an unmagnetised ferromagnetic substance, the domains point in [blank_start]different[blank_end] directions and [blank_start]cancel[blank_end] one another out. In a magnetised ferromagnetic substance, the domains point in [blank_start]the same[blank_end] direction to create defined poles.
To magnetise these domains one can either:
Align them by stroking the substance with a permanent magnet
OR
Use electricity to align them and create [blank_start]and elctromagnet[blank_end]
