magnetic dipole

[mag′ned·ik ′dī‚pōl]
(electromagnetism)
An object, such as a permanent magnet, current loop, or particle with angular momentum, which experiences a torque in a magnetic field, and itself gives rise to a magnetic field, as if it consisted of two magnetic poles of opposite sign separated by a small distance.

Using the above numbers in equation (22) gives the magnetic dipole moment: [micro] = 4.
Our measurements show that the magnetic torque method can be used to measure magnetic dipole moments of many permanent magnets with very good accuracy.
This particle mediates the magnetic interaction between magnetic dipoles thereby establishing the magnetic interaction as one separate from the electromagnetic interaction and converts all of classical magnetism into a quantum theory.
It leads, under appropriate conditions, to the inverse square law for magnetic poles as well as an inverse higher-order law for magnetic dipoles given by
Devis Iellici, R&D Director of Antenova, commented "Agilis A10346 is a small 40x10x3mm3 switchable magnetic dipole antenna offering design flexibility for global mobile device manufacturers.
This magnetic compass was designed originally as an automobile accessory, and we marked a visible arrow on the rotator by luminous paint parallel to the magnetic dipole of the ferrite.
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.
The simulation runs iteratively, each time altering the magnetic dipoles so that they fit the data better.
The model could approximate this magnetic field using a few virtual magnetic dipoles.
However, the magnetic field arrangement for the Aharanov and Bohm experiment is equivalent to a line of magnetic dipoles so, if while sitting on a permanent magnet, another magnet is held at arm's length above the head and then slowly lowered, phase reversals of the dowsing response are obtained successively.
If each actin monomer is in a mixed state out of the electrostatic and magnetostatic ones, thermal agitations would easily destroy a coherent alignment of the magnetic dipoles along the filament because of the presumed absence of any coherent correlation between the two individual states.
