Magnetism and Matter: Why Some Things Stick

  1. Magnetic Basics: Magnetism comes from moving electric charges inside atoms.
  2. Electron Spins: In magnetic materials, many electrons spin in the same direction, creating strong fields.
  3. Iron Family: Metals like iron, nickel, and cobalt are naturally magnetic.
  4. Everyday Stick: Paperclips, nails, and fridge doors stick because they contain iron.
  5. Temporary Magnetism: Non-magnets can become magnetic for a short time when near a strong magnet.
  6. North and South: All magnets have two poles—opposites attract, like poles repel.
  7. Earth’s Magnet: Our planet is a giant magnet, guiding compasses with its magnetic field.
  8. Magnetic Domains: Tiny regions inside materials align to make them strongly magnetic.
  9. Not Everything Sticks: Aluminum, copper, and wood don’t respond to magnets.
  10. Technology Power: Magnetism drives motors, speakers, credit cards, and even MRI machines.
