Current carrying wire produces:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Magnetic field only
A current in a wire is a steady drift of free electrons past the fixed positive ions of the metal. The wire as a whole remains electrically neutral, since the number of electrons equals the number of positive charges in every part of it.
A charge produces an electric field; a moving charge produces a magnetic field as well (Oersted's observation).
NCERT (2026-27):
Introduction – “… During a lecture demonstration in the summer of 1820, Danish physicist Hans Christian Oersted noticed that a current in a straight wire caused a noticeable deflection in a nearby magnetic compass needle.”
Introduction – “… Oersted concluded that moving charges or currents produced a magnetic field in the surrounding space.”
