Magnetic Flux in a sentence

Magnetic flux The magnetic flux density ( magnetic field ) having the unit Wb/m 2 ( Tesla ) is denoted by B, and magnetic flux is defined analogously: : with the same notation above.

If an object has a certain magnetic flux over its surface area, and that area shrinks to a smaller area, but the magnetic flux is conserved, then the magnetic field would correspondingly increase.

With turns of the winding oriented perpendicularly to the magnetic field lines, the flux is the product of the magnetic flux density and the core area, the magnetic field varying with time according to the excitation of the primary.

The expression dΦ/dt, defined as the derivative of magnetic flux Φ with time t, provides a measure of rate of magnetic flux in the core and hence of EMF induced in the respective winding.

Adiabatic invariance The properties of magnetic mirrors can be derived using the adiabatic invariance of magnetic flux under changes in magnetic field strength.

The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron ; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.

Because of their symmetry, toroidal cores allow a minimum of the magnetic flux to escape outside the core (called leakage flux ), so they radiate less electromagnetic interference than other shapes.

One hypothesis is that of "flux freezing", or conservation of the original magnetic flux takes place during the formation of the neutron star.

This is ironic because Maxwell was one of the major developers of what we now call "electric flux" and "magnetic flux" according to the second definition.

By adding a " magnetic core " made of a ferromagnetic material like iron inside the coil, the magnetizing field from the coil will induce magnetization in the material, increasing the magnetic flux.

For example, a Hall sensor integrated into a ferrite ring (as shown) can reduce the detection of stray fields by a factor of 100 or better (as the external magnetic fields cancel across the ring, giving no residual magnetic flux ).

In disagreement to the statement in the previous section, a measurement of the magnetic flux density very close to the magnet is related to by the formula : The effective magnetic dipole can be written as : Where is the volume of the magnet.

Loops of magnetic flux well-up from the solar body and fill with hot solar plasma. citation Due to the heightened magnetic activity in these coronal loop regions, coronal loops can often be the precursor to solar flares and coronal mass ejections (CMEs).

The overall strength of a magnet is measured by its magnetic moment or, alternatively, the total magnetic flux it produces.

When the electric current flowing through such a coil changes, it produces a magnetic flux, which is a change in the magnetic field over a given area.

Babaev says that originally research held that quantum vortices pass through superconductors each carrying one quantum of magnetic flux.

As the magnet moves with respect to the coil, the magnetic flux linkage of the coil changes.

A varying current in the transformer's primary winding creates a varying magnetic flux in the transformer core and a varying field impinging on the transformer's secondary winding.

Banks and other clearing houses employ automation equipment that relies on the magnetic flux from these specially printed characters to function properly.

Both of these EMF's, despite their different origins, can be described by the same equation, namely, the EMF is the rate of change of magnetic flux through the wire.
