Who among the following discovered that a wire carrying electric current can attract or repel another wire next to it that's also carrying electric current?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Andre-Marie Ampere.
The discovery that a wire carrying an electric current can attract or repel another wire carrying an electric current was made by André-Marie Ampère. In the early 19th century, Ampère conducted experiments and formulated Ampère's Law, which describes the magnetic force between two current-carrying conductors. This discovery laid the groundwork for the field of electromagnetism, helping to establish the relationship between electricity and magnetism, and contributing to the development of modern electrical engineering.
