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.

This analogy is based on the formation of magnetic dipoles, like electric dipoles, but consisting of two point fictitious magnetic charges (hereinafter--the dipole model of magnetization).
With purpose of simulating the borehole electromagnetic method, the vertical magnetic dipoles were set in the arbitrary point in the model.
As shown in Figure 2, the horizontal slot can be equivalent as a magnetic dipole and it works in the half-wavelength mode.
Theoretically, for simple geometries of the detection channel, it would be possible to calculate the minimum detectable magnetic dipole as a function of the distance and orientation between the pick-up coil and the magnetic source, once the intrinsic noise of the channel is known [20].

To create this training base, we have proceeded by calculating the NF radiated by an electric and then magnetic dipole for different orientations.
Figure 14 shows the correct position of the magnetic dipole identified at the MOSFET.
In this work, transition parameters have been presented such as wavelengths, oscillator strengths, and transition probabilities (or rates) for magnetic dipole (M1) and electric quadrupole (E2) transitions of low-lying levels of the spectrum in neutral boron (B I).
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.
The company said that its Agilis A10346 is a small switchable Magnetic Dipole Antenna (MDA) offering dual mode GSM/LTE capabilities and also Wi-FI, Bluetooth and WiMAX in a single structure.
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.
