<p class="MsoPlainText"><span lang="en-NL">A Magnetic System is the toy model for the motion of a charged particle moving on a Riemannian Manifold endowed with a magnetic field.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="en-NL">Solutions for such systems are called Magnetic Geodesic and preserve the Kinetic Energy. One of the most relevant investigative interest in the theory is to understand the existence and in case the topological nature
of Closed Magnetic Geodesic</span><span lang="EN-US">s</span><span lang="en-NL"> (periodic solution</span><span lang="EN-US">s</span><span lang="en-NL">) in a given level of the energy. I will introduce the Magnetic Curvature, an object which encodes the geometrical
properties coming from the Riemannian Curvature structure together with terms of perturbation due to the magnetic interaction. We will see how a positive curved Magnetic System carries a Contractible Closed Magnetic Geodesic for small energies.</span><span lang="EN-US"><o:p></o:p></span></p>
