For example, the CGS volume magnetic susceptibility of water at 20 °C is 7.19 × 10 −7, which is 9.04 × 10 −6 using the SI convention, both quantities being dimensionless. Whereas for most electromagnetic quantities, which system of quantities it belongs to can be disambiguated by incompatibility of their units, this is not true for the ...
The magnetization is the negative derivative of the free energy with respect to the applied field, and so the magnetization per unit volume is = , where n is the number density of magnetic moments. [1]: 117 The formula above is known as the Langevin paramagnetic equation.
The chi (Tongyong Pinyin chih) is a traditional Chinese unit of length. Although it is often translated as the " Chinese foot ", its length was originally derived from the distance measured by a human hand, from the tip of the thumb to the tip of the forefinger, and is similar to the ancient span .
imaginary unit: unitless electric current: ampere (A) ^ Cartesian x-axis basis unit vector unitless current density: ampere per square meter (A/m 2) impulse: kilogram meter per second (kg⋅m/s) jerk: meter per second cubed (m/s 3)
Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal n̂, d is the dipole moment between two point charges, the volume density of these is the polarization density P.
The Chi-Chi's Hepatitis A outbreak served as a wake-up call for the food industry and led to the implementation of new food laws, which have helped prevent similar outbreaks from occurring in the ...
The Quadrantid meteor shower is one of the strongest, and quickest, meteor showers of the year. Here’s what you need to know to observe it during peak activity.
There's an interesting situation brewing at the top of the NFC right now. Three teams — the Philadelphia Eagles, Detroit Lions and Minnesota Vikings — could potentially end the season with the ...
