Question
State the research done by scientists on electromagnetism after Oersted's observation.
✓
Answer
→After the observation of Oersted, in 1864 James Maxwell examined the laws governing electricity and magnetism and concluded that light is an electromagnetic wave.
→Scientist Hertz discovered radio waves and, Jagdish Bose, Marconi produced radio waves experimentally by the end of the $19^{\text {th }}$ century.
→ This led to the invention of devices for generation, amplification, transmission and detection of electromagnetic waves in the $20^{\text {th }}$ century.
