biot [′bī·ät]
(electricity) (optics) A unit of rotational strength in substances exhibiting circular dichroism, equal to 10-40times the corresponding centimeter-gram-second unit. Biot a unit of current strength in the OGSB (cm-g-sec-biot) system of units proposed for magnetic measurements; it is rarely used, and the State Standard of the USSR makes no provision for it. It is named after the French scientist J. B. Biot. One biot is taken to be a DC current which, when flowing in two straight parallel conductors of infinite length and negligibly small circular cross section separated by 1 cm in a vacuum, produces a force of 2 dynes per cm of length between the conductors. One biot equals 10 amperes. Want to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit the webmaster's page for free fun content. |
