Michael Kimwele answered on 17 Jul 2025:
Magnets attract certain materials due to the alignment of electrons within those materials. In most substances, electrons spin in random directions, canceling out their magnetic effects. However, in materials like iron, cobalt, and nickel, electrons tend to align their spins in the same direction, creating a magnetic field. When a magnet is brought near these materials, their internal magnetic fields align with the external magnetic field, resulting in attraction.

Hey,
🧲 Why do magnets attract some materials?
Magnets attract materials like iron, nickel, and cobalt because of something cool called magnetic domains.
🧠 Here’s the science:
Inside these metals are tiny magnetic regions (called domains) that act like mini magnets.🔄 In normal materials, these domains point in random directions, so they cancel each other out.
➡️ But in magnetic materials, when a magnet comes close, it forces the domains to line up, and boom! The material gets pulled toward the magnet!
🧲✅ Attracted materials: iron (like nails), steel, cobalt, nickel
❌ Not attracted: plastic, wood, paper, aluminumSo, magnets attract materials that have domains ready to line up!
