why and when does a current carrying conductor kept in a magnetic field experience force? List the factors on which direction of this force depends?
plzzz answer me quickly

Theory: 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 current carrying conductor has moving electrons inside it.Which generates an electric field surrounding the conductor.If the conductor is placed in a magnetic field, then the existing electric field and the introduced magnetic field interacts.This interaction produces force.
Think of yourself sitting in a room alone. Now one enters the room and that for sure will effect you or your activities. Calculation/measurement of this effect is the FORCE that the conductor experiences.
P.S_ If you seek a mathematical expression of this force,I’m giving it below.
F = q(E+v × B) - this’s known as Lorentz force law, where,
F=total force, E=electric field, v=velocity of the conducting particles,
B= magnetic field introduced, q= electronic charge & F,B,v,E are vectors.
hope it helps
