anisotropy energy meaning in Hindi

Examples

1. where " F " anis, the anisotropy energy density, is a function of the orientation of the magnetization.
2. Changing the magnetization of the material to any other direction takes additional energy, called the " " magnetocrystalline anisotropy energy " ".
3. The anisotropy energy is lowest when the individual magnetic moments are aligned with the crystal lattice axes thus reducing the width of the domain wall.
4. The magnetocrystalline anisotropy energy of a ferromagnetic crystal can be expressed as a power series of direction cosines of the magnetic moment with respect to the crystal axes.
5. The magnetic moments in the hard phase do not rotate until the external field is high enough that the exchange energy density in the transition region is comparable to the anisotropy energy density in the hard phase.
6. So flux closure domains will only form where the magnetostatic energy saved is greater than the sum of the " exchange energy " to create the domain wall, the magnetocrystalline anisotropy energy, and the magnetoelastic anisotropy energy.
7. So flux closure domains will only form where the magnetostatic energy saved is greater than the sum of the " exchange energy " to create the domain wall, the magnetocrystalline anisotropy energy, and the magnetoelastic anisotropy energy.
8. Some sources define a wall energy " E W " equal to the sum of the exchange energy and the magnetocrystalline anisotropy energy, which replaces " E ex " and " E k " in the above equation.
9. The width of the domain wall varies due to the two opposing energies that create it : the magnetocrystalline anisotropy energy and the exchange energy ( J _ { \ mathrm { ex } } ), both of which tend to be as low as possible so as to be in a more favorable energetic state.
10. where is the height of the energy barrier, a product of the magnetic anisotropy energy density and volume; is the Boltzmann constant, the temperature and their product the thermal energy; and is a length of time, characteristic of the material, called the " attempt time " or " attempt period " ( its reciprocal is called the " attempt frequency " ).
