Answer 1

$\boxed{Explained\:Answer}$

______________________________

==============================================

■According to Fleming’s left hand rule if we stretch the thumb, the centre finger and the middle finger of our left hand such that they are mutually perpendicular to each other.

■If the centre finger gives the direction of current and middle finger points in the direction of magnetic field then the thumb points towards the direction of the force or motion of the conductor.

==============================================

Answer 2

$hi \: ...$

Here's your answer ...

Fleming's Left hand rule states that :

Whenever a current carrying conductor is placed in a magnetic field, the conductor experiences a force which is perpendicular to both the magnetic field and the direction of current.

According to Fleming's left hand rule, if the thumb, fore-finger and middle finger of the left hand are stretched to be perpendicular to each other as shown in the illustration at left, and if the fore finger represents the direction of magnetic field, the middle finger represents the direction of current, then the thumb represents the direction of force.

Fleming's left hand rule is applicable for motors.

hope this helps you
