The dipole magnetic moment of Neptune is about 2.2 × 10 17 T·m 3 (14 μT·R N 3, where R N is the radius of Neptune). Neptune's magnetic field has a complex geometry that includes relatively large contributions from non-dipolar components, including a strong quadrupole moment that may exceed the dipole moment in strength. By contrast, Earth ...
Schematic representation of a planetary dipole magnetic field in a vacuum (right side) deformed by a region of plasma with infinite conductivity. The Sun is to the left. The configuration is equivalent to an image dipole (green arrow) being placed at twice the distance from the planetary dipole to the interaction boundary. [1]
The dipole model of the Earth's magnetic field is a first order approximation of the rather complex true Earth's magnetic field. Due to effects of the interplanetary magnetic field (IMF), and the solar wind , the dipole model is particularly inaccurate at high L-shells (e.g., above L=3), but may be a good approximation for lower L-shells.
Over the last two centuries the dipole strength has been decreasing at a rate of about 6.3% per century. [13] At this rate of decrease, the field would be negligible in about 1600 years. [35] However, this strength is about average for the last 7 thousand years, and the current rate of change is not unusual. [36]
English: Absolute magnitude of the axial dipole component of Earth's magnetic field from 1600 to 2020, according to three models: CALS3k.4, gufm1, and IGRF-12. Date 29 May 2016
Magnetic field strength: H: Strength of a magnetic field A/m L −1 I: vector field Magnetic flux density: B: Measure for the strength of the magnetic field tesla (T = Wb/m 2) M T −2 I −1: pseudovector field Magnetic moment (or magnetic dipole moment) m: The component of magnetic strength and orientation that can be represented by an ...
Love, passion and self-expression are front and center for you this month, Aries. Once Venus enters your sign on Feb. 4, your charm and magnetism get a significant boost, making you feel like the ...
The size of the induced dipole moment is equal to the product of the strength of the external field and the dipole polarizability of ρ. Dipole moment values can be obtained from measurement of the dielectric constant. Some typical gas phase values given with the unit debye are: [7] carbon dioxide: 0; carbon monoxide: 0.112 D; ozone: 0.53 D
