Pedro Viteri  pjv267 3/3/08 Physics 103M: Laboratory 3  1. Introduction  The main objective of the laboratory 3 of the physics course 103m, was to show how the potential energy  directly relates to the kinetic energy, after transforming all into kinetic energy. The potential energy was  produced by the magnetic fields of different magnets.  The energy in a magnetic field is proportional to the capacity of the magnets and to the distance between them.  The magnetic potential is represented as U(x), where x is the distance between the magnets, and the force  exerted is F= -dU/dx, as we can see the magnetic potential energy is inverse proportional to the distance x. So if  the magnets are closer, the force will be greater than if they are far away. The pole of the magnets does  influence in the direction of the force, because the negative and the positive create a force, like a tension, pulling  the magnets together. The positive with a positive create a force like compression pushing the magnets away  from each other. In this experiment we just consider the opposing force between the magnets.  The configuration of the magnets will provide potential energy, similar to the gravitational potential energy.
