HERE IS YOUR ANSWER-
Fleming's left hand rule is used to determine the direction of force exerted on a current carrying wire placed in a magnetic field.
Fleming's left-hand rule states that “When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force perpendicular to both the field and to the direction of the current flow.” It was invented by John Ambrose Fleming.
