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

(N/A) current-carrying conductor produces its own magnetic field around it. When this field interacts with an external magnetic field,it experiences a mechanical force.
The direction of this force depends on two factors:
$1$. The direction of the electric current flowing through the conductor.
$2$. The direction of the external magnetic field.
The rule used to determine the direction of this force is $Fleming's \text{ } Left-Hand \text{ } Rule$.
Statement of $Fleming's \text{ } Left-Hand \text{ } Rule$: Stretch the thumb,forefinger,and middle finger of your left hand such that they are mutually perpendicular to each other. If the forefinger points in the direction of the magnetic field,the middle finger points in the direction of the current,then the thumb will point in the direction of the force (or motion) acting on the conductor.
