Question

What did Oersted conclude from the experiment ?

• A. The current carrying wire must be acting as a magnet for the compass needle to deflect.
• B. The current carrying wire gets heated up and causes the compass needle to deflect.
• C. The current carrying wire sets up air currents that makes the compass needle to deflect.
• D. None of the above

Answer 1

The correct option is A The current carrying wire must be acting as a magnet for the compass needle to deflect.

The deflection of the compass needle, whenever there is current in the wire show that a current carrying wire produces a magnetic field around it, which is essentially saying the current carrying wire must be acting as a magnet.
