Magnetic Fields

Some articles on magnetic fields, magnetic field, field, magnetic:

Ap And Bp Stars - Magnetic Fields
... They also have stronger magnetic fields than classical A or B type stars in the case of HD 215441, reaching 33.5 kG (3.35 T) ... Typically the magnetic field of these stars lies in the range of a few kG to tens of kG ... In most cases a field which is modelled as a simple dipole is a good approximation and provides an explanation as to why there is an apparent ...
Spacecraft Magnetometer - Magnetometer Types - Search-coil Magnetometer
... also called induction magnetometer, are wound coils around a core of high magnetic permeability ... Search coils concentrate magnetic field lines inside the core along with fluctuations ... The benefit of these magnetometers is that they measure alternating magnetic field and so can resolve changes in magnetic fields quickly, many times per second ...
Scanning SQUID Microscopy - Instrumentation
... to the extreme sensitivity of the SQUID probe to stray magnetic fields, in general some form of magnetic shielding is used ... with a superconducting "can" (all superconductors repel magnetic fields via the Meissner effect) ... itself can be used as the pickup coil for measuring the magnetic field, in which case the resolution of the device is proportional to the size of the SQUID ...
Stellar Magnetic Field - Field Generation
... Stellar magnetic fields, according to solar dynamo theory, are caused within the convective zone of the star ... activity destroys the star's primordial magnetic field, then generates a dipolar magnetic field ... at different rates for various latitudes—the magnetism is wound into a toroidal field of "flux ropes" that become wrapped around the star ...
Spin (physics) - Magnetic Moments
... Particles with spin can possess a magnetic dipole moment, just like a rotating electrically charged body in classical electrodynamics ... These magnetic moments can be experimentally observed in several ways, e.g ... deflection of particles by inhomogeneous magnetic fields in a Stern–Gerlach experiment, or by measuring the magnetic fields generated by the particles themselves ...

Famous quotes containing the words fields and/or magnetic:

    Or seen the furrows shine but late upturned,
    And where the fieldfare followed in the rear,
    When all the fields around lay bound and hoar
    Beneath a thick integument of snow.
    So by God’s cheap economy made rich
    To go upon my winter’s task again.
    Henry David Thoreau (1817–1862)

    We are in great haste to construct a magnetic telegraph from Maine to Texas; but Maine and Texas, it may be, have nothing important to communicate.
    Henry David Thoreau (1817–1862)
