$\underline \mathbb{RULE\:1}$

»FLEMING'S LEFT HAND RULE

It states that if the fourfiner, thumb and the middle finger of left hand are stretched mutually perpendicular to each other such that the fore finger point along the direction of external magnetic field ;middle finger indicates the direction of current then the thunb point outwards the direction of force acting on the conductor.

$\underline \mathbb{RULE\:2}$

»FLEMING'S RIGHT HAND RULE

It states that if the forefinger middle finger and thumb of the right hand are stretched at right angles to each other with the fore finger in the direction of the magnetic field and the thumb in the direction of the motion of the wire then the induced current in the wire is in the direction of the middle finger.
