How do dipoles make a metal magnetic?
1 Answer

Dipoles must align paralell to each other.
Explanation:
Firstly, magnetization refers to the density of any magnetic dipole moments in a magnetic body ( a ferrous metal).
In general, dipoles must align paralell to each other.
Shortly, a metal can be magnetized by these aspects:
- Electricity :
Electric currents align magnetic domains.
-
Below Curie temperature
-
Ferromagnetism :
Ferromagnetism occurs in some metals, this phenomenon forms permanent magnets. The atoms in these metals have an unpaired electron, so its spin aligns when a magnetic field is induced.
- DOMAINS :
They are areas containing atomic dipoles. When these dipoles become aligned in a single direction, the material exhibits magnetic properties such as iron. Strong magnetic domains can induce others.
