Question
Magnetic effects of current were discovered by
- Faraday
- Oersted
- Ampere
- Joule
Hint:
Magnetic effects of current were discovered by Oersted.
The correct answer is: Oersted
- Hans Christian Oersted made the discovery of the magnetic effect of an electric current in 1820.
- By placing a compass near a long, straight wire carrying electricity and observing its deflection, he showed how the effect works.
- The compass needle was also deflected in the other direction by changing the current's direction.
