The magnetization of a bar magnet of length 5 cm,cross-sectional area 2 cm^(2) and magnetic moment 1 Am^(2) is

A bar magnet has length 3 cm, cross-sectional area 2 cm^(3) and magnetic moment 3 Am^(2) . The intensity of magnetisation of bar magnet is

A bar magnet of magnetic moment 10Am^(2) has a cross sectional area of 2.5xx10^(-4)m^(2) . If the intensity of magnetisation of the magnet is 10^(6)A//m , then the length of magnet is

The moment of a magnet is 3 xx 10^(-1)A m^(2) and the length of the magnet is 10cm. The pole strength of the magnet is (in A.m)

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

A short bar magnet of magnetic moment 20Am^(2) has a cross sectional area of 1.5xx10^(-4)m^(2) . If the intensity of magnetisation of the magnet is 10^(5)A//m . The length of magnet is
