What does Fleming's left hand rule state?

To know the direction of motion of conductor.

We use flemings right hand rule

If we strech middle finger,fore finger and thumb such as to be supposed they are mutually perpendicular to each other

Then middle finger shows direction magnetic field

Fore finger shows direction of current and thumb shows direction of motion

Fleming's Left Hand Rule: Stretch out the first three fingers of your left hand such that they are mutually perpendicular to each other, align first finger in direction of magnetic field, middle finger in direction of current then the thumb will give the direction of force acting on the conductor.

Arrange three fingers of right hand mutually perpendicular to each other, if the first figure indicates the direction of flux, thumb indicates the direction of motion of the conductor, and then the middle finger will point out the direction of induced current.

Fleming's Right Hand Rule: Stretch out the first three fingers of your right hand such that they are mutually perpendicular to each other, align first finger in direction of magnetic field, thumb in direction of relative motion of conductor with respect to field then the middle finger will give the direction of induced EMF.
