The demagnetizing field, also called the stray field (outside the magnet), is the magnetic field (H-field) [1] generated by the magnetization in a magnet. The total magnetic field in a region containing magnets is the sum of the demagnetizing fields of the magnets and the magnetic field due to any free currents or displacement currents.
The mines detected the increase in the magnetic field when the steel in a ship concentrated the Earth's magnetic field over it. Admiralty scientists, including Goodeve, developed a number of systems to induce a small "N-pole up" field into the ship to offset this effect, meaning that the net field was the same as the background.
Iconographic Collections. Keywords: E. Walker; Florence Nightingale; W.J. Simpson. Health administration, healthcare administration, healthcare management or hospital management is the field relating to leadership, management, and administration of public health systems, health care systems, hospitals, and hospital networks in all the primary, secondary, and tertiary sectors.
Ministries of health in several sub-Saharan African countries, including Zambia, Uganda, and South African, were reported to have begun planning health system reform including hospital accreditation before 2002. However, most hospitals in Africa are administered by local health ministries or missionary organizations without accreditation programs.
This demagnetizing field is applied opposite to the original saturating field. There are however different definitions of coercivity, depending on what counts as 'demagnetized', thus the bare term "coercivity" may be ambiguous: The normal coercivity, H Cn, is the H field required to reduce the magnetic flux (average B field inside the material ...
If the magnetic field is now reduced monotonically, M follows a different curve. At zero field strength, the magnetization is offset from the origin by an amount called the remanence. If the H-M relationship is plotted for all strengths of applied magnetic field the result is a hysteresis loop called the main loop.
Healthcare is a vital and pervasive issue; it influences all aspects of societies. It has medical, social, political, ethical, business, and financial ramifications. In any part of the world healthcare services can be provided either by the public sector or by the private sector, or by a combination of the two. Healthcare can be provided in ...
In the United States, management of a single institution (e.g. a hospital) is also referred to as "medical and health services management", "healthcare management" or "health administration". Health systems management ensures that specific outcomes are attained, that departments within a health facility are running smoothly, that the right ...
