Solution

Step 1: Reason for experiencing the force
If a current-carrying conductor produces a magnetic field and exerts a force on a magnet, the magnet should also exert a force on the current-carrying conductor.
Step 2: Write the factors on which direction of the force depends.
(1) Direction of current
(2) Direction of magnetic field
Step 3: Name and State the rule
Fleming's Left Hand Rule
“When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force perpendicular to both the field and the current flow's direction".
