    Answer: The correct answer is " He discovered electromagnetism after seeing a compass needle deflected by a flowing electric current".

    Explanation:

    Hans Oersted worked with electricity and magnetism. He discovered that electric current produces magnetic field. The electricity and magnetism are interrelated to each other.

    He discovered that the current carrying conductor produces magnetic field around it. When he placed a compass needle near a current carrying conductor then the compass needle shows the deflection which shows that there is magnetic field around the current carrying wire.

    Therefore, the correct option is (B).
