Class 10ScienceMagnetic Effects of Electric CurrentMagnetic Field due to a Current-carrying Conductor
Medium$(i)$ $A$ compass needle gets deflected when brought near a current-carrying conductor. Why?
$(ii)$ What happens to the deflection of the needle when the current in the conductor is increased?
$(ii)$ What happens to the deflection of the needle when the current in the conductor is increased?
(N/A) $(i)$ $A$ current-carrying conductor produces a magnetic field around it. When a compass needle is brought near this conductor,the magnetic field of the conductor exerts a force on the magnetic needle,causing it to deflect.
$(ii)$ The strength of the magnetic field produced by a current-carrying conductor is directly proportional to the magnitude of the current flowing through it. Therefore,when the current in the conductor is increased,the magnetic field strength increases,which leads to a greater deflection of the compass needle.
