    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.  The space environment is filled with charged particles,  electrons and ions, that may be deposited on a  1 -  100 microns sized particle.  The orbits of such charged particles  have been modeled in earth orbit, with the dipole magnetic field superposed on the gravity field. An initial study of  this problem has been conducted. Figures  1 illustrates a 600 second time frame of  particles in a 300 kilometer altitude Earth orbit with  a 5.7' inclination.  The solid line is the pure Kepler problem.  The dashed lines are the paths taken by various sized particles with  a single positive charge of 1.6x10-'~ coulombs. The additional  energy required  to deflect these particles from a Kepler orbit comes from the deposition of  charge at the initial stage in the calculation.  From there the energy of  the particle is  conserved since both the gravitational  and magnetic forces are conservative, i.e. $F d r  = 0. The orbit of  1 micron sized particles has been computed and the results  a r e  shown in figures 2 through 5.  The results of  this numerical exercise in magneto-orbital dynamics a r e  rather unexpected, but  appear physically  correct when studied.  The particle was set in a 2000km orbit with a 5.7'  inclination.  Figure 2 displays how the magnetic field torques the orbital plane.  Figure 3 then shows how the orbit is flipped over and shoved toward  the north pole.

    "This was by far the best project management workshop I've attended!" "Excellent. This workshop met my expectations in every way. Thanks!" "Great! Glen did an awesome job. It was all valuable, especially Glen's real world experience." "A lot of information presented in a well organized and structured fashion." "I enjoyed the discussion of the different types of project teams structures." "Very useful information that was presented in a timely and organized manner." "I found the resource leveling most valuable. Good interaction with the audience." "Very useful. Especially the information on risk management, communication management, and change management." "Very good. Defining the team roles and responsibilities was valuable." "I could have used this years ago. Great use of visuals. Good reference manual. Great tool!" "I'd recommend this class to others. I plan to implement the techniques immediately, especially the skills on organizing and tracking." "Very well done. Glen is very knowledgeable of the subject matter." "Excellent information. I appreciated the speaker's experience and information base." "This was very helpful. I will be sending the rest of my project team to this course." "Most valuable were the three types of project specifications: implementation, non-implementation, and post-implementation." "The work breakdown structure and resource leveling you taught are great methods." "Very professional and very effective. I will be able to apply the things I learned immediately!" "Glen is a very good presenter. The delivery was informative, interactive, and great! Of particular value was the task analysis and PERT." "Excellent for all project managers. I found the project planning skills most valuable." "The risk analysis charts were excellent. Lots of new information." "I found the need to identify all the team members in a project and effective communication with them most valuable." "I enjoyed this class, especially the information on project organization.
