Question

Why does a current carrying conductor kept in a magnetic field experience force? On what factor does the direction of this force depend? Name and state the rule used determination of direction of current

Answer 1

When a current-carrying conductor is placed in a magnetic field the wire experiences a force due to the interaction between the field and the magnetic field produced by the moving charges in the wire.

The current carrying conductor generates it own magnetic field around it. This  interracts with the external magnetic field. When two magnetic fields interact there will be attraction and repulsion between them based on the direction of the external magnetic field and the direction of the current in the conductor. That is why the conductor experiences a force.
            and is rule is kwnow as fleming rule..

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

If a conductor of length "l" moves at right angles to a magnetic field,B, e.m.f induced in the conductor.
it based on Fleming rule.
