A metallic conductor is suspended perpendicular to the magnetic field of a horse shoe magnet. The conductor gets displaced towards left when a current is passed through it. What will happen to the displacement of the conductor if the: (i) current through it is increased ? (ii) horse-shoe magnet is replaced by another stronger horse-shoe magnet? (iii) direction of current through it is reversed?

A metallic conductor is suspended perpendicular to the magnetic field

1.	A metallic conductor is suspended perpendicular to the magnetic field of a horse shoe magnet. The conductor gets displaced towards left when a current is passed through it. What will happen to the displacement of the conductor if the: (i) current through it is increased ? (ii) horse-shoe magnet is replaced by another stronger horse-shoe magnet? (iii) direction of current through it is reversed?
Answer» Solution :(i) On increasing the current flowing through METALLIC CONDUCTOR, the force experienced by it is proportionately increased because `Fprop l`. (ii) On using a stronger horse-shoe magnet the magnetic force increases because `F prop B` . (iii) On reversing the direction of current the direction of force is reversed and conductor is DISPLACED towards right instead of LEFT direction.
