Neutral points of a bar magnet , Other Engineering

Assignment Help:
  • Fix a drawing paper on a drawing board with help of drawing pins.
  • Place a magnetic needle on the drawing paper to identify geographical north and south poles.
  • Mark north, south to north indicates horizontal component of earth's magnetic field B.
  • Place a bar magnet in the middle of drawing paper such that the north pole of the bar magnet faces geographical north of earth and south pole of the magnet faces geographical south of the earth.
  • Sketch the boundaries of bar-magnet.
  • Draw magnetic lines starting from north pole of a bar magnet to south pole at difference points using a small compass. The magnetic lines of force are obtained as shown in figure.
  • Two null points N1 and N2 are obtained on either side of the bar magnet at equal distances from its centre ‘O' we will observe that magnetic needle in the compass do not show any specific direction it sets itself in an arbitrary direction at N1 and N2
  • The null points obtained are on equatorial line. At these null points the magnetic field induction due to earths magnetism (B0) and magnetic field induction due to bar magnet are equal in magnitude and opposite in direction 
  • Hence the resultant magnetic field becomes zero.
