Question

explain why when the current is switched on through a wire the needle of compass give nearly gets deflected from its north south position​

Answer 1

Answer:

because of electro magnetic induction

Explanation:

in the process of electro magnetic induction when a current carrying conductor is placed in specific place/area and if we change its direction continuously because of this magnetic field is produced and due to this in this case the pressure is applied in the magnet due to magnetic field and due the as per the direction of curren the magnet get deflected from South to north position ✌️

Answer 2

Explanation:

when the current is switched on through a wire the needle of compass give nearly gets deflected from its north south position because when the current will flow from the wire the compass pulled like a magnet and they two pulled each other for attraction. And we also know that a compass is a tiny magnet.So that's why when the current is switched on through a wire the needle of compass give nearly gets deflected from its north south position. And this effect is called magnetic effect of electric current.
