The Magnetic Force Observation and Demonstration under the Condition of Microgravity

In micro-gravity environment,the gravity affects almost disappeared,some dynamical variables such as magnetic force may play a main role in the physical process.In order to observe the change process of the magnetic force,we have built a short-term micro-gravity experimental system,and observed the image of the magnetic force's change process.Finally we give the result of the magnetic force's change process.
