1. magnetic field strength

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents,: ch1  and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.: ch13 : 278  A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment. Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function assigning a vector to each point of space, called a vector field. In electromagnetics, the term "magnetic field" is used for two distinct but closely related vector fields denoted by the symbols B and H. In the International System of Units, the unit of H, magnetic field strength, is the ampere per meter (A/m).: 22  The unit of B, the magnetic flux density, is the tesla (in SI base units: kilogram per second2 per ampere),: 21  which is equivalent to newton per meter per ampere. H and B differ in how they account for magnetization. In vacuum, the two fields are related through the vacuum permeability, B / μ 0 = H {\displaystyle \mathbf {B} /\mu _{0}=\mathbf {H} } ; but in a magnetized material, the quantities on each side of this equation differ by the magnetization field of the material. Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.: ch1  Magnetic fields and electric fields are interrelated and are both components of the electromagnetic force, one of the four fundamental forces of nature. Magnetic fields are used throughout modern technology, particularly in electrical engineering and electromechanics. Rotating magnetic fields are used in both electric motors and generators. The interaction of magnetic fields in electric devices such as transformers is conceptualized and investigated as magnetic circuits. Magnetic forces give information about the charge carriers in a material through the Hall effect. The Earth produces its own magnetic field, which shields the Earth's ozone layer from the solar wind and is important in navigation using a compass.

1. magnetic field strength

Magnetic field strength, also known as magnetic field intensity or magnetic field H, is a measure of the amount of magnetizing force in a magnetic material. It is essentially a quantity that determines the ability of a magnetic field to induce a magnetic response in a specific medium. This parameter is usually shown in amperes per meter (A/m) or oersted (Oe) units. It's important to note that the magnetic field strength differs from the magnetic field (or magnetic flux density), with the latter being influenced by the magnetic properties of the medium in which it exists.

### Examples of magnetic field strength in a Sentence

1. The Inouye Solar Telescope's all about the magnetic field, to unravel the Sun's biggest mysteries, we have to not only be able to clearly see these tiny structures from 93 million miles away but very precisely measure their magnetic field strength and direction near the surface and trace the field as it extends out into the million-degree corona, the outer atmosphere of the Sun.
