The magnetic dipole moment
is now expressed as follows:
Therefore, the ground state energy dependence becomes almost linear in accordance with formula (9) for n = 0, resulting in the magnetic dipole moment
of a conical nanotube almost independent on the magnetic field and equal to the tangent of the aperture angle.
* By rotating (without translating) a magnetic dipole moment
m in an external magnetic field B = [[mu].sub.0]H, Maxwell found previously from the change in potential energy W in Art.
Our measurements show that the magnetic torque method can be used to measure magnetic dipole moments
of many permanent magnets with very good accuracy.
Equations (3a)-(3b) imply that the magnetic dipole moment
obeys the transformation (see, e.g., Ref.
Case m = [m.sub.0] Relation between density of an electric current [j.sub.[perpendicular to]] and the magnetic dipole moment
is defined from (45) in case when the magnetic dipole moment
m is directed lengthwise z:

Here, the scalars [p.sub.-,2] and [m.sub.-,2] are the magnitudes of the electric dipole moment vector [p.sub.-,2] and the magnetic dipole moment
vector [m.sub.-,2], respectively.
In Section 3, the distributions of free and magnetization currents resulting from this magnetic dipole are carefully considered and various possible definitions for the magnetic dipole moment
In the magnetostatic problem, the magnetic dipole moment
of the ring is determined from the condition of zero magnetic induction through the wire, such that the magnetic field component normal to the surface vanishes on the ring (i.e., [??] x ([H.sup.inc] + [H.sup.sc]) = 0, where [??](r) is the surface normal at r).
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.
Primarily, the electric and magnetic dipole moments
are the basic foundations for making metamaterials.
