magnetic flux density units


Figure \(\PageIndex{3}\) (bottom) shows an example.

This particle will experience no force.

Magnetic fields are an intrinsic property of some materials, most notably permanent magnets. The other common magnetic flux density units are gauss, maxwell per square inch and weber per square centimeter.

Suddenly, the particle perceives a force. In fact, webers per square meter is the unit for flux density. https://doi.org/10.21061/electromagnetics-vol-1 Licensed with CC BY-SA 4.0 https://creativecommons.org/licenses/by-sa/4.0.

For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. A bar magnet has “poles” identified as “N” (“north”) and “S” (“south”).

The electromagnetic force also gives rises to the electric field, and it is only limited intuition, grounded in classical physics, that leads us to perceive the electric and magnetic fields as distinct phenomena.

The SI unit for magnetic flux is the weber (Wb).

U, F. gilbert (Gb) 10/4π. To begin, let us consider the effect of a magnetic field on a electrically-charged particle. The short answer is that this terminology is somewhat arbitrary, and in fact is not even uniformly accepted.



It is sufficient to accept this apparent strangeness as fact and proceed accordingly. Therefore, not only is current the source of the magnetic field, the magnetic field also exerts a force on current. Φ. maxwell (Mx), Gּcm 2. The metric system unit of magnetic flux density is tesla. We want to hear from you. The SI unit for magnetic flux density is the tesla which is equivalent to webers per square meter.

From this, we infer that the underlying mechanism is the same – i.e., the vector field generated by a current-bearing coil is the same phenomenon as the vector field associated with a permanent magnet. Before offering a formal definition, it is useful to consider the broader concept of the magnetic field. This situation is shown in Figure \(\PageIndex{2}\) (top). The reader would be well-justified in wondering why the force exerted by the magnetic field should perpendicular to \({\bf B}\). For example, a coil of wire bearing a current is found to influence permanent magnets (and vice versa) in the same way that permanent magnets affect each other. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. We refer to \({\bf B}\) as magnetic flux density, and therefore tesla is a unit of magnetic flux density.

Any quantity that is obtained by integration over a surface is referred to as “flux,” and so it becomes natural to think of \({\bf B}\) as a flux density; i.e., as flux per unit area. The magnetic flux density of a magnet is how the strength of a magnet is described most of the time.

In SI, this combination of units is known as the tesla (T).

Also, explore many other unit converters or learn more about magnetic flux density unit conversions. Free online magnetic flux density converter - converts between 11 units of magnetic flux density, including tesla [T], weber/square meter, weber/square centimeter, weber/square inch [Wb/in^2], etc. It can be thought of as the density of the magnetic field lines - the closer they are together, the higher the magnetic flux density.

Magnetic flux density is a vector field which we identify using the symbol \({\bf B}\) and which has SI units of tesla (T). Magnetic flux density, magnetic induction. The other common magnetic flux density units are gauss, maxwell per square inch and weber per square centimeter.

Next, a magnetic field appears; perhaps this is due to a permanent magnet or a current in the vicinity.

We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. The basic phenomenon is probably familiar, and is shown in Figure \(\PageIndex{1}\). This concept is illustrated in Figure \(\PageIndex{4}\) for a permanent bar magnet and Figure \(\PageIndex{5}\) for a current-bearing coil. The unit was named in 1960 after the Serbian-American electrical engineer Nikola Tesla. 1 Tesla is equal to 1 weber per square meter.
B. gauss (G) d. 10-4. tesla (T), Wb/m 2.

These are questions for which classical physics provides no obvious answers. In engineering electromagnetics, the preference for referring to \({\bf B}\) as a “flux density” is because we frequently find ourselves integrating \({\bf B}\) over a mathematical surface. We’ll get to the details about direction and magnitude in a moment, but the main idea is now evident. The magnetic flux density (magnetic field) is an invisible field surrounded by magnets and electric currents. Summarizing: The magnetic field describes the force exerted on permanent magnets and currents in the presence of other permanent magnets and currents. For our present purposes – and for most commonly-encountered engineering applications – we do not require these concepts.

This means that flux density B is a value which includes magnetizability and magnetic flux H does not include magnetizability.
