Magnetism

Grade 4 · Science and Technology 1 min read

Introduction

Magnetism is a special power that some objects have to attract or repel other objects.

What Makes an Object Magnetic?

  • Some objects, like iron nails and paper clips, are naturally magnetic.
  • You can turn some objects into magnets by rubbing them against a magnet.
  • Magnets have two ends: the North Pole and the South Pole. Opposite poles attract each other, while similar poles repel each other.

Everyday Examples of Magnetism

  • Magnetic Compass: A compass uses the Earth's magnetic field to show directions.
  • Fridge Magnets: Fridge magnets stick to the fridge because of magnetism.
  • Magnetic Toys: Some toys use magnets to stick together.

Fun Activity

You can make your own magnet by rubbing a paperclip against a magnet repeatedly. Test if the paperclip can now attract other small metal objects like pins or nails.

Remember

  • Magnets have two poles: North and South.
  • Opposite poles attract, similar poles repel.
  • Some objects are naturally magnetic, while others can become magnetic by rubbing them against a magnet.
