In recapitulation, the angle between TN and MN is the angle of variation, while the angle between MN and the deflected position of the needle when under the influence of the boat's magnetic field is the angle of deviation.
Ukuphinda ngokufutshane ii-engile phakathi ko TN no Mn yi-engile yeendidi ngelixesha i-engile phakathi ko MN nendawo engaboniswanga yenaliti xa ingaphantsi kwempembelelo yesikhephe samasimi kamazibuthe yi-engile yokuphambuka.
