How many magnetic types and how made magnet

Permanent Magnets:
These steadfast companions retain their magnetic quality over time. Their secret lies in the alignment of their internal microcrystalline structure.
Manufacturing: Crafted from materials like alnico (aluminum, nickel, and cobalt) or ferrite, permanent magnets undergo special processing. They emerge resilient, resisting demagnetization.
Temporary Magnets:
These fleeting enchanters lose their magnetism swiftly. Think of them as magnetic chameleons.
Examples: Soft iron bars temporarily magnetize when near a strong magnetic field but revert to their non-magnetic state once the field vanishes.
Electromagnets:
These magical creations harness electric currents to weave magnetic fields. When the current flows, they transform into powerful magnets; when it ceases, they return to their mundane state.
Construction: Coils of wire wrapped around a core (often mild steel) amplify the magnetic field. Think of them as switchable magnets—activated by electricity.
