πŸ“š Quick Study Guide

  • 🧲 Magnetism is a force that attracts or repels certain materials, like iron, nickel, and cobalt.
  • 🌍 The Earth itself is a giant magnet, which is why compasses work.
  • 🧭 Compasses use a magnetic needle that aligns with the Earth's magnetic field, pointing towards the North Pole.
  • πŸ’‘ Electromagnets are created when an electric current flows through a wire wrapped around a metal core. The strength of the electromagnet can be controlled by changing the amount of current.
  • πŸ”Š Many everyday devices use magnets or electromagnets, such as speakers, motors, and generators.
  • βš•οΈ MRI (Magnetic Resonance Imaging) machines use powerful magnets to create detailed images of the inside of the human body.
  • πŸš‚ Maglev trains use powerful magnets to levitate above the tracks, allowing for very fast and smooth travel.
