A Wikipedia page, with the Wikidata link highlighted. Every Wikipedia article (and many other pages, such as templates) should have an ID on our sister project, Wikidata. The ID is a series of digits prefixed "Q", and so is referred to as a QID.. This page is a simple guide to finding that QID.
The H-field strength inside a long solenoid wound with 79.58 turns per meter of a wire carrying 1 A is approximately 1 oersted. The preceding statement is exactly correct if the solenoid considered is infinite in length with the current evenly distributed over its surface.
where H 0 is the applied magnetic field due only to the free currents and H d is the demagnetizing field due only to the bound currents. The magnetic H-field, therefore, re-factors the bound current in terms of "magnetic charges". The H field lines loop only around "free current" and, unlike the magnetic B field, begins and ends near magnetic ...
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.
Slayback's Missouri Cavalry Regiment was a cavalry regiment of the Confederate States Army during the American Civil War.Formed as Slayback's Missouri Cavalry Battalion, the unit consisted of men recruited in Missouri by Lieutenant Colonel Alonzo W. Slayback (pictured) during Price's Raid in 1864.
H magnetic field strength ampere per metre: A/m A⋅m −1: F magnetomotive force: ampere: A = Wb/H A R magnetic reluctance: inverse henry: H −1 = A/Wb kg −1 ⋅m ...
assuming B and H are parallel. In the microscopic formulation of electromagnetism, where there is no concept of an H field, the vacuum permeability μ 0 appears directly (in the SI Maxwell's equations) as a factor that relates total electric currents and time-varying electric fields to the B field they generate.
The magnetic field lines lie in a plane perpendicular to the wire. If the direction of the current is reversed, the direction of the magnetic field reverses. The strength of the field is directly proportional to the magnitude of the current. The strength of the field at any point is inversely proportional to the distance of the point from the wire.
