Question

what is flemings right hand rule

Answer 1

Fleming's right hand palm rule :-
this is relationship between direction of field , current and force .
according to this rule /

open the right hand and place it so that tips of the finger pointing in the direction of magnetic field and thumb in the direction of velocity of positive charge( current) , then the palm face towards the force.

Answer 2

Fleming's right hand rule :

The forefinger, the middle finger and the thumb of the right hand are held in three mutually perpendicular directions. If the forefinger points along the direction of the magnetic field and the thumb along the direction of motion of the magnetic field and the thumb along the direction of motion of the conductor, then the middle finger points in the direction of induced current.
