“How a Simple Wire Became a Magnet 🔥 The Discovery of Magnetic Fields”
**“In 1821, Ferdinand Oersted discovered something that changed physics forever —
a simple metallic wire carrying electric current behaves like a magnet!
People thought iron filings made that beautiful pattern…
But Ferdinand saw what others didn’t:
✔ Magnetic lines were not created by iron
✔ They were already present around a current-carrying wire
✔ This invisible force is the magnetic field
Electricity + magnetism = Electromagnetism
And this discovery powers motors, generators, speakers — almost everything around us today!
