Abstract
In this paper we consider oscillating non-exact magnetic fields on surfaces with genus at least two and show that for almost every energy level \(k\) below a certain value \(\tau _+^*(g,\sigma )\) less than or equal to the Mañé critical value of the universal cover there are infinitely many closed magnetic geodesics with energy \(k\).
