On which of the following factor, the direction of deflection of a magnetic needle of a compass depends when the compass is kept near a current carrying wire?
Electricity and magnetism are said to be inter-related to each other. A current carrying conductor has a magnetic field around it. So, when a compass is brought near to it, we can observe a deflection in the compass. Similarly, a battery is the source of the electric current. What will be the deflection, when we bring a compass near a 3 V cell (battery)?
Why does a compass needle get deflected when placed in a magnetic field? is it because the north pole of the compass needle and north pole of the magnet deflect?
