The product of the magnitude of the pole stregth and the magnetic length is

The product of the magnitude of the pole strength and the magnetic length is

The product of pole strength and the magnetic length of a magnetic is called __________

The earth's magnetic field may be considered to be due to a short magnet placed at the centre of the earth annd oriented along the magnetic south-north direction. The ratio of the magnitude of the magnetic field on the earth's magnetic equator to that at the magnetic poles is

Two identical thin bar magnets each of pole strength 'm' and magnetic length are placed at 90^@ to each other with north pole of one magnet touching the south pole of the other magnet. The magnetic moment of the system is

A: If a bar magnet is cut into two equal halves then magnetic dipole moment of each part is half that of the original magnet. R: magnetic dipole moment is the product of pole strength and magnetic length.

The product of the length of the magnet and its pole strength is called the moment of a magnet or Magnetic moment. If 'm' is the pole strength and 2l is the length of the magnet then, the moment of the magnet or Magnetic moment is given by. M =m xx 2l . Also, Magnetic moment is a vector quantity, with its direction from south pole to north pole along its axial line. If a bar magnet of magnetic moment 80 units be cut into two halves of equal lengths the magnetic moment of each half will be

Two bar magnets are placed at right angle to each other with the north pole of one touching the south pole of the other . If both the magnets have pole strength m and length 2L, then the mgnetic moment of the combination will be .
