Please can u tell me all about Fleming right and left hand rule , and right grip rule ?
Fleming's Left Hand Rule the direction of the force, for electric motors (Dc)
Fleming's Right Hand Rule the current by the force,for electric generators (AC)
Right Grip Rule- Direction of the Magnetic field when Direction of current is given,for current carrying conductors
Thank God Fleming stooped making rules or there would be a left foot rule or a right foot rule ;) well right grip was not by Fleming no wonder it is easier to use
