magnetic field saturated

  • Permeability and Saturation Magnetism and

    The specific relationship of force to flux (field intensity H to flux density B) is graphed in a form called the normal magnetization curve. It is possible to apply so much magnetic field force to a ferromagnetic material that no more flux can be crammed into it. This condition is known as magnetic saturation.

    B Magnetic induction, is the magnetic field induced by a field strength, H, at a given point. It is the vector sum, at each point within the substance, of the magnetic field strength and resultant intrinsic induction. Magnetic induction is the flux per unit area normal to the direction of the magnetic path.
