when the current is switched on through a wire a compass needle get nearby gets deflected from its north- south position. explain
Answers
when the current is switched on through a wire compulsory gets nearby gets deflected from its north to south permission this is why because of the magnetic field where there is magnetic field the motion of the needle will be in that direction only this is because of the paradise left hand rule it is happened to that and you to the magnetic induction of that the current is induced with the help of a magnetic field this is the reason why the needle is reflecting this is all because of the magnetic field magnetic force
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.
