Magnetism:

1. Properties of magnets:
   • Magnets have two poles: north and south.
   • Opposite poles attract, while like poles repel.
   • Magnets can attract certain materials, like iron, nickel, and cobalt.
   • They can also attract or repel other magnets.
2. Grouping materials to magnetic and non-magnetic:
   • Magnetic materials: Iron, steel, nickel, and cobalt.
   • Non-magnetic materials: Wood, plastic, glass, and rubber. 🔩🚫
3. Common applications of magnetism:
   • Fridge magnets hold notes and pictures. 🧲📝
   • Magnets are used in compasses to show directions. 🧭
   • Magnetic strips on credit cards store information. 💳
   • Electric motors and generators use magnets to work. ⚙️💡
4. Making and using magnets:
   • Rubbing iron or steel with a magnet can make it magnetic.
   • Once magnetized, magnets can pick up paperclips, nails, or other small metal objects. 📎🔩
   • Magnets can also be used to find hidden nails or screws in walls or floors. 🔍🔩
