Option 1 is the correct statement. Fleming’s left hand rule is used to determine the direction of the force acting on a current-carrying conductor in a magnetic field. According to this rule, if you point your left hand`s thumb in the direction of the current, and extend your fingers, the direction in which your fingers curl represents the direction of the force. This rule is based on the principle that when a current-carrying conductor is placed in a magnetic field, a force is exerted on the conductor perpendicular to both the direction of the current and the magnetic field.

Option 2 is incorrect because Fleming’s right hand rule is used to determine the direction of the induced current when a conductor moves through a magnetic field, not for the direction of force on a current-carrying conductor in a magnetic field.

Option 3 is also incorrect as both left-hand and right-hand rules have different applications. The left-hand rule is specifically for force on a current-carrying conductor, while the right-hand rule is for the direction of induced current.

Option 4 is incorrect as Fleming`s rules are directly related to the concept of magnetic fields and their interaction with current-carrying conductors.
