Question

force on a current carrying conductor in a magnetic field please say about this topic seminar because tomorrow seminar is there please​

Answer 1

Answer:

A current carrying conductor placed in a magnetic field experiences a force. If the direction of the field and that of current are mutually perpendicular to each other, then the force acting on the conductor will be perpendicular to both and that can be determined using the Fleming's left-hand rule.

A.M Ampère suggested that if a current carrying conductor produces a magnetic field and exerts a force on the magnet, then a magnet should also exert a force on a current carrying conductor.

Eg :- if an Aluminium rod is suspended horizontally by a wire between the poles of a horse shoe magnet and current is passed through the wire, then the aluminium rod is displaced. if the direction of current is reversed, the direction of displacement is also reversed. The force exerted is maximum if the conductor is perpendicular to the magnetic field.

Finally, Ampère was able to establish that the attractive force between two parallel current carrying wires is proportional to the product of the two currents, and falls off like one over the perpendicular distance between the wires.

hope my answer helps you.
