Question

when the current is switched on through the wire a compass needle kept nearby gets deflected from its north south position. explain ​

Answer 1

WHEN the current is switched on through a wire a compass needle kept nearby gets deflected it's not South position because of the magnetic effect of electricity.when the current flows through the wire the the compass needle kept nearby deflect because it feels a pull from the wire and get deflected from its north south position

Answer 2

Answer:

When current is passed through the coiled wire, it deflects the compass near it from its north-south position like a magnet. This is called magnetic effect of the current. As we know that needle of the compass is made up of a thin magnet. When this needle comes in contact with another magnet then the like poles of the magnet repel each other and opposite poles attract each other. So the deflection is seen in the needle. In this case the wire behaves like a magnet and causes deflection in needle of the compass.
