Give reasons for the following
The needle shows deflection when kept near acurrent carrying wire.
According to class 10
Answers
Answer:
the current carrying conductor produces a magnetic field around it this magnetic field applied force on a magnetic needle of compass and thus the needle show deflection
Explanation:
When a magnetic needle is brought closer to a current carrying conductor then the magnetic needle it gets deflected because the magnetic field of the current carrying conductor exerts a force on the magnetic needle, making it move from one direction to the other.
When a magnetic compass is brought close to a current carrying wire there is deflection in the compass due to the formation of magnetic field. The magnetic field lines around a long wire which carries an electric current form concentric circles around the wire. The direction of the magnetic field is perpendicular to the wire.
The deflection increases when the current is increased because the magnitude of the field is directly proportional to the strength of the electric current. That is, stronger the electric field, stronger the magnetic field.
Hope this helps mate ☺️.
