Practice question · Put in order
Order the historical development of electromagnetism leading to Maxwell's equations.
- Coulomb's law for electric force (1785)
- Maxwell adds displacement current (1865)
- Faraday's law of induction (1831)
- Hertz detects electromagnetic waves (1887)
- Ampere's law for magnetic force from currents (1826)
Hints
- The individual laws were found before they were unified.
- Experimental confirmation of the waves came after the prediction.
Show the answer
- Coulomb's law for electric force (1785)
- Ampere's law for magnetic force from currents (1826)
- Faraday's law of induction (1831)
