a

In a magnetic field, Fleming's left-hand rule determines the direction of the force on a current-carrying conductor.

b

In a magnetic field, Fleming's right-hand rule determines the direction of the force on a current-carrying conductor.

c

 In a magnetic field, both the left-hand and right-hand rules can be employed to determine the direction of force on a current-carrying conductor.

When a current-carrying conductor is exposed to an external magnetic field, it is subjected to a force that is perpendicular to both the field and the current flow direction.

When a current-carrying conductor is exposed to a magnetic field, it experiences a force. Fleming's Left Hand Rule can be used to determine the direction of this force.

When a moving conductor is exposed to a magnetic field, an electric current is generated in the conductor. Fleming's Right-Hand Rule may be used to determine the direction of the induced current.

John Ambrose Fleming was the one who came up with the idea.

Fleming's Left-Hand Rule:-

When the thumb, centre finger, and forefinger of the left hand are arranged at right angles to each other, the thumb points in the direction of magnetic force, the centre finger points in the direction of current, and the forefinger points in the direction of a magnetic field.

It's a type of electric motor.

The rule's aim is to determine the motion direction of an electric motor.

Fleming's Right-Hand Rule:-

The thumb represents the direction of motion of the conductor, the index finger represents the direction of the Magnetic Field, and the middle finger represents the direction of the induced current when the thumb, centre finger, and forefinger of the right hand are arranged at right angles to each other.

It's a material that's employed in electric generators.

When a conductor travels in a magnetic field, the rule is used to determine the direction of induced current.
