Who first demonstrated the link between electricity and magnetism?

  1. Hans Christian Oersted
  2. Michael Faraday
  3. Andre Marie Ampere
  4. James Clerk Maxwell
Show answer and solution

Correct answer: A. Hans Christian Oersted

1. In 1820, Oersted noticed that a compass needle deflected when placed near a current-carrying wire. 2. This was the first evidence that electric currents produce magnetic effects. 3. Faraday later discovered electromagnetic induction, the reverse phenomenon. 4. So Oersted established the original link between electricity and magnetism. _Source: syllabus Science Ch 13 'Magnetic Effects of Electric Current' (learncbse.in extract)_
