magnetic dipole moment

n
(General Physics) a measure of the magnetic strength of a magnet or current-carrying coil, expressed as the torque per unit magnetic-flux density produced when the magnet or coil is set with its axis perpendicular to the magnetic field. Symbol: m or j Also called: magnetic moment Compare electromagnetic moment

Electrons don't spin, it is just shorthand for "maintaining their magnetic dipole moment.
The magnetic dipole moment is a vector quantity, so it has both magnitude (energy) and direction.
The magnetism arises from the magnetic dipole moment of unpaired electrons in the d- or f-orbitals.
Applied to the already known solar system bodies, the methods developed by Zuluaga and his team are able to predict the so-called magnetic dipole moment of bodies ranging from Ganymede to Jupiter to the right order of magnitude.
tCP], the value of the horizontal field becomes approximately equal to the vertical field (as electric dipole moment x[eta] = magnetic dipole moment, where t] is the intrinsic impedance of the medium) and because the original source field responsible for radiation is electric and magnetic for dipole and loop antenna respectively, an almost pure CP is achieved.
It can be seen that the induced current flows annularly along the SRR's arms, which produces the magnetic dipole moment and leads to the negative permeability effect of the SRR.
As it has been intensively studied for the quasi-static resonance [8], the electric field component of the incident wave can excite circulating currents along SRRs which in turn give rise to a magnetic dipole moment perpendicular to the SRR plane, that is, along z according to our coordinates definition [1,3].
ABSTRACT--As a means to determine the dipole moment of a permanent magnet, as well as the horizontal component of the Earth's local magnetic field, a cylindrical neodymium magnet with axial magnetic dipole moment is suspended from a thin vertical string with its axis horizontal.
MRI creates images using the principles of Nuclear Magnetic Resonance, and it is possible in the scallop, because its soft-tissued body is filled with small biological "magnets," the most abundant and responsive of which is the proton, the nucleus of the hydrogen atom, and it possesses a nonzero angular momentum or nuclear spin, which creates a magnetic dipole moment along their rotational axis.
This is because typical small compasses have a very small magnetic dipole moment, and consequently their mutual magnetic interaction is much smaller than the Earth's ambient magnetic field.
