The two body dynamics of an orbiting particle is usually governed by Newton's laws of gravity and mechanics. Here the Kepler problem has been studied with the addition of the Lorentz force of magnetism. For micrometeoroids and small man made debris particles electromagnetic interactions may become important.

Designed by Chapman Associates and manufactured in the U.K. by K-Tech Limited. Overview 'MICRON' is a very small radio-controlled switching system, fully CAA approved for security use on aircraft, in which the miniature Radio-Switch has the capability to acknowledge automatically any valid commands received from an operator using a hand-held Command Unit. It operates at very low power in the licence-exempt UHF band, is battery powered, and all functions are managed by intelligent low-power microprocessors. Main features The 'MICRON' Radio-Switch produces virtually no RF radiation when receiving, which makes it ideally suited for use in locations where it may be positioned close to other very sensitive electronic equipment, and also greatly facilitates its compliance with ETSI-ETS 300 220 and similar regulations. The basic Radio-Switch unit is only 52mm x 36mm x 12mm and weighs just 13 grams (excluding antenna and connecting leads). When fitted in a plastic case (optional), its dimensions become 57mm x 41mm x 20mm. The Radio-Switch consumes only 250uA (average) when using battery economiser. Two different output configurations are available, each capable of switching an external DC load of up to 500mA, as detailed below:- (a) A miniature latching relay which provides one fully isolated pair of changeover contacts. This latching relay only requires a short pulse to 'flip' it from one state to the other and then retains that position, even if power is removed, until it is 'flipped' back to the previous state. Two versions of the Radio-Switch using the latching-relay are available, one for use on a DC supply voltage of 4.5-9 volts and the other for 8-16 volts. OR (b) A solid-state high-side power switch. This version switches the 'MICRON' DC supply voltage (which can be anywhere in the range 5-16 volts) to its output lead whenever the Radio-Switch is commanded to the 'ON' position. It is totally silent in operation but does not provide the ful
